Atlas.Ti 6 vs NVivo 9: A Comparison

Follow-up to Potential uses of CAQDA software packages from A.Hariri's

A couple of days ago I received an e-mail from one of my research blog (in Arabic) followers asking for my opinion on choosing NVivo or Atlas.Ti. I've sent her a summary of some of the issues that I faced when I tried both of them.

Today, I was asked by a friend of mine, Salma Patel of why I chose Atlas.Ti over NVivo as well, therefore, I decided to write a detailed post about this to help those who may be looking into this as well.

I found that Atlas.Ti 6 and NVivo 9 were two of the most used software packages out there. So, I went ahead to do some research and I decided to try them both. I ended up choosing Atlas.Ti although I was much inclined to use Nvivo for the following reasons:

Nvivo stores everything within 1 project file. There is the obvious risk of losing everything if this file becomes corrupted. Yes, I will make backups, but I still want to be safe. Furthermore, what if there is a bug in the software itself? It wouldn't really be able to access anything.	Atlas.Ti has a project file that only stores projects information and certain details. Documents/PDFS do not have to be imported into the project. Atlas.Ti can get them where they are :). In the worst case scenario that something may be wrong with the file, you can still access external documents such as PDFs.
I already have a working structure of my documents (Thanks to Mendeley), why would I need to copy those files over to NVivo too? Waste of space in my opinion. Some could say delete the PDFs from Mendeley and just have the record for each document. Well, this can be done but then, I wouldn't really be using Mendeley's nice features such as effective searching within PDFs and pictures, etc..	Because Atlas.Ti will reach your documents where they are, you could have Mendeley arrange your library into a certain structure, then, you ask Atlas.ti to link those documents to your project. Note: You may want Mendeley to sort your documents into folders based on Years at the the top level so that you could easily see which document your passage you are reading if you output a list of passages within Atlas.Ti. I have also had Mendeley rename the files so that Author's names are in the begining of the file name for the same reason too.
Because it relies on 1 project file, there is no doubt that the file size would become bigger as you go on.	Project file remains very small.
I found NVivo to be a bit slow although I was working with an empty project...	Still going fast
The bigger the project size the laggier NVivo becomes.	Would not lag as much because the project file which runs the show is relatively small.
Until recently, NVivo had a very bad support for PDFs and I was surprised to see the company taking their time (months!!!) to release an update that would fix this although I would expect this to be a core feature in this age! I haven't looked into the update which they said should fix any PDF issues because I had already decided to go with Atlas.Ti.	Excellent support for PDFs!
Due to the above point, I believe that NVivo should look more into updating more frequently, especially when certain things should be fixed and are demanded to be fixed by customers in the forums	Many updates released continuously which improves the way Atlas.Ti works or fixes bugs and so on. In fact, I think I've seen 4 minor updates for Atlas.Ti within the last 2-3 months. It tells me as a customer that they care!
Although a bit slow sometimes, the UI is better than Atlas.Ti which was one of the main reasons I was seriously hoping to use it. However, the late release of the update and the slow response killed any chance I had of using it.	UI not as nice as NVivo, but, as I started working more with Atlas.Ti, I started to appreciate the UI and how it is arranged. However, it is obvious that I am more interested in performance.

These are what I think some of the key issues I based my comparison on, when it comes to features, both software packages offer very similar set of features.

After writing this comparison, I have to say that I do not hate NVivo, I simply think it wasn't for me. Others may find working with NVivo is better for their own reasons. I still follow the development of both NVivo and Atlas.Ti, and I still retweet some of their announcements and so on to my Research Blog (in Arabic) followers.

I hope some of you out there find this helpfu! and I am happy to learn about your experiences with any of the mentioned software packages.

Potential uses of CAQDA software packages

About a year ago, I was looking into Computer assisted qualitative data analysis software (CAQDA) software packages that may help me in doing my literature review by allowing me to code certain passages within documents into codes that I could then easily explore or retrieve.

I think one of the potentials I saw in some CAQDA software packages is that if you code useful passages within lots of papers and documents into codes (which are similar to keywords), this will make it easier for you to retrieve those stored passages of texts within different documents.

For example: if I have read 100 PDFs and assigned things that I believe relevant to my research into codes, it would be much easier to just output the passages that belong to a certain code within those 100 PDFs in 3-5 pages (since other information within each document will be hidden) showing where every passage came from and how they can relate to each other (You can use relationships between them too!). This would surely be much easier than having to check all those 100 PDFs to try and find bits and pieces here and there that belong to the topic I am trying to write about.

Another potential where I personally think CAQDA could help is building a rich research library of journal papers and different documents over the years. Because, in many cases, a PhD might be the first step of your research career, especially if you are a lecturer or someone that is interested in publishing journal papers in the same field. I guess what I am trying to say is, lets assume that while doing your PhD you come across 100 journal papers that you consider important in your research field. After that, you become a lecturer at some university where you are expected to do more research. So you read more journal papers and you assign more information to codes within the CAQDA software. After a couple of years, you could have a very rich library of papers that you have already read and classified into certain codes or keywords.

After that, all you have to do really when you want to write a journal paper is ask the CAQDA to output information related to a keyword and start writing.

For instance, you may choose to first write a background, so, you output background information which you store in a code. Next, you may choose to become more specific, so, you may want to identify previous gaps and even gaps that may still be in need of research. You output information assigned to a code "Gaps in....." and you find all different arguments by different authors, etc...

I believe that using a CAQDA helps a lot when it comes to writing, if it was used by the researcher while he was doing his literature review.

I know that some would argue that it is not good to just read certain parts of the paper and assign them and just forget the rest of the paper may see like taking things out of context, but this is only true if the researcher himself didn't pay attention to that.

Of course I am only scratching the surface here as most CAQDA have much more advanced and useful features such as reports & networks diagrams where you could visually show the relationship between different passages. For instance, you could show a number of authors disagreeing with author A while may others are supporting him.

I have been working with a CAQDA software (Atlas.Ti) mainly as part of my literature review as I believe it keeps me organised and helps me find information that I have already looked into much faster than I would usually do. I will continue to use it as I go on with my PhD and I hope that I learn more about it and try the various features available and be able to share what I find or anything new later on.

Wordpress Mac Permissions Issues with Zend Server CE

If you have installed Zend Server CE on your computer to use as a development server, you may have ran into the issue of Automatic update not working on Wordpress. This is the function that usually updates your Wordpress plugins and Wordpress system or core files. Furthermore, another related problem that you will likely to have as a result of this is that you won't be able to have Wordpress edit your .htaccess to change the way your blog URLS look like.

The cause of this problem is that the Apache user used by Zend Server CE (User: daemon, Group: daemon) is not given enough permissions to be able to make changes to your files on your Mac. The solution to this should be simple, at least it worked for me right away.

The Solution:

Open your Terminal application (Applications -> Utilities)
Use the following commands in bold:

Navigate to your htdocs folder that was created by Zend Server CE using something like:
cd /usr/local/zend/apache2/htdocs
Change the user of your blog folder which resides within the htdocs folder. In my case my blog folder is called blog, so I used this command:
sudo chown -R daemon blog
Change the permissions of the folder using:
sudo chmod -R g+w blog

Now, try to update your Wordpress plugins or Wordpress system itself (core files), this should have solved your Wordpress Mac permission issues. In my case, I didn't restart and it worked. If it doesn't work rightaway on your development environment, try restarting your Mac.

Note: The solution above worked for me because I don't allow any network access to my development environment, if you for some reason need better security, you should probably check Zend Server's documentation to follow their suggestions with regard to how to make your development environment safer.

Hope these steps work for you!

Mendeley

Writing about web page http://www.mendeley.com/

From Mendeley's website:

Mendeley is a free reference manager and academic social network that can help you organize your research, collaborate with others online, and discover the latest research.

Automatically generate bibliographies

Collaborate easily with other researchers online

Easily import papers from other research software

Find relevant papers based on what you're reading

Access your papers from anywhere online

Read papers on the go, with our new iPhone app

View more features…

Mendeley is one of the new software/services that provides advanced references management features.

What I liked in Mendeley

What I really liked in Mendeley is that:

It can sync your references between multiple PCs/Macs.
Allows you to read, annotate & comment on PDFs from within the software itself.
User interface is very nice!
Can be set so that it starts watching your resources folders, adding every paper/document that is added to these folder to the library itself while tagging these auto added documents as 'To be reviewed' so that you can review and confirm that every bit of information is correct.

If you have been using Endnote (like me), you will be happy to know that you can export your Endnote library to Mendeley directly. Ofcourse, this doesn't mean that you can't use Endnote at all if you swich to Mendeley. You can work on Mendeley and if for any reason you wanted to insert bibliographies from Endnote or for any other reason, you can export your final library to Endnote and use it.

Research & Decide yourself!

Lastly, I just wanted to know that although I see Mendeley as a good choice for referencing management, etc.. However, I don't want to influence your decision in anyway!

You should spend sometime comparing/researching whatever software you are aware of, for example, for me, I ended up comparing Endnote, Zotero and Mendely. I quickly took Endnote out of the equation for a number of reasons such as its lack of easy sync features and inability to edit PDFs within the software. Lastly, I ended up choosing Mendeley over Zotero because:

Zotero is a Firefox plugin. Therefore, it relies on another software which really adds another variable into the situation that could go wrong. For instance, what if there were some problems in Firefox? What if Zotero become unstable or incompatible for any reason with one of Firefox's future updates? Lastly, what if Zotero affects Forefox's performance?
Mendeley's ability to edit PDFs within the same software is just great!
The ability to watch folders within Mendeley is nice!

Therefore, it really depends on your work style and the set of features you might require which can be available in a certain software and not in the others.

Do you use any of these?

If you are using one of the mentioned software, I would really like to hear your experience. There might be features that I am not aware of in any of these mentioned software.

NVivo 9 Tutorials

One of my friends told me that his friend suggested that he uses NVivo for management of sources and qualitative data analysis. I have never heard of NVivo before so I wanted to give it a try. I downloaded the software and installed but still didn't really have the time to give it a try.

Furthermore, while searching for relevant reviews. I found that there is a good number of people who have suggested the use of NVivo in Academic Research and most certainly by PhD students.

I am really interested in finding what others who have used/are using NVivo think about it. I know that there is a need for some coding, but since I am going through the new journal papers I am downloading I will probably scan be able to code quickly.

One of the advantages of using NVivo is that it allows me to see all the sources related to one node (Theme or topic). Which really saved time especially if you are talking about having 100s of papers in your library. Being able to assign certain parts of papers to different nodes/topics is a really nice and very helpful feature!

I don't want to waste a lot of my time learning about NVivo 9 and testing it until I know for sure that it can help. Therefore, I haven't started using it.

I am actually hoping that some members of staff or some visitors would shed some light as to if NVivo 9 is indeed helpfull for me as a PhD student or not.

So, if you have any experience using NVivo 9 or any previous version, please let me know how it was. Did it help you get better results? Was it worth it?

Below are a number of videos that explain certain basic parts in NVivo 9, in case you wanted to learn more about it.

Thumbnails in Wordpress 2.9+ and 3.0+

Now that Wordpress added a thumbnail feature (2.9+), we longer need to assign custom fields and give them values each time we write a blog post. Insted, while writing a blog post, there is a small panel or block to the side that allows us to choose a thumbnail for the post.

However, for people like me, who have been using custom fields to show pictures for sometime, there is a decision to be made. Should we stick to the custom fields and just continuou using them or should we start using the core thumbnails featre instead?

Well, you don't really have to the choose one of these two, you will keep using them both. How you ask? Well, simply, stop using custom fields for any new posts you write and use the thumbnail feature to assign thumbnails to blog posts. Then, edit your templates and add some simple conditions so that Wordpress checks whenever a blog post is viewed if it has a custom field thumbnail or a core wordpress 2.9+ thumbnail. By doing this, your old blog posts thumbnails will still show and your new thumbnails, the one you assign using the new feature will also show.

Honestly, I was very worried about having to choose one of these two, and since I am not a programmer/developer/coder, I was worried that I wouldn't be able to figure this out. However, with some thinking and imagination and with the help of a number of great Wordpress articles I was able to use my thumbnails in my Blog homepage. Not only that, but using some of the new features related to thumbnails, I was actually able to set specific sizes for the different pages in my blog. For example, on my homepage, all posts thumbnails are 100px x 75px. However, when a visitor clicks on a certain blog post to view it, he is shown the same picture but in a different size, say 200px x75px. This is really nice and it's really simple to achieve.

As I said, I am not a programmer and I was able to figure this out with the help of the following resources. There is no reason why you shouldn't be able to get similar results :). I would also like to thank each one of those blog authors:

If anyone (not good with coding as I am) wants to look at the code I have used in my template pages to show the thumbnails, I would be happy to share.

If you want to check what I was talking about, you can visit my Arabic Research Blog. Don't ming the language, but make note of the thumbnails then follow some of them to the post view page to see if the thumbnail's dimension will change or not. Please note that because some of the thumbnails are actually cropped, they might not show in a bigger size if you follow them to the post.

Wordpress Link Library plugin

Writing about web page http://yannickcorner.nayanna.biz/wordpress-plugins/link-library/

Wordpress Link Library plugin is one of the most useful plugins I have used for Wordpress. Not only it allows you to show your links along with their categories in a nice way that can be easily formatted, it also allows your Wordpress blog visitors to suggest new links, this was very helpful on one of my websites as I needed a way to allow others to do this.

Other features include: the ability to set an RSS icon for each link and show/hide links descritions. ofcourse, there are many more!

I have been using Wordpress Link Library plugin for quite some time on my Arabic Research Blog, in the Research Links Library and Link Library Wordpress plugin have proven to be a very useful and stable plugin.

Lastly, the Link Library plugin's developer Yannick, is also very useful and helpful when it comes to answering any questions related to any of the Wordpress plugins that he developed, and his blog is the biggest indicator of his will to help others. Thanks Yannick!

To view some examples of how this plugin can be used, visit the Link Library plugin and look under examples or configuration.

Lastly, if you find this plugin very helpful (like I did), please don't hesitate to donate, as this will help keep the project going and help Yannick with any costs related to the maintenance of his blog or as a little incentive for him to keep going :).
