Atlas.ti is a useful software, see  http://atlasti.com/

Thank you Dear laurens. I also would like to thank you because of your very attractive topics and contents of your researches and articles. I am one of your followers.

All the best

Nvivo 10 is also useful. See http://www.qsrinternational.com/products_free-trial-software.aspx for a free trial and more information.

Thank you Ms. Rhonda Nicole Balzarini!

I am just following the matter!

Good luck and thanks again.  

Various versions of this question have been asked several times on ResearchGate, and I hope I speak for the majority of posters when I say that the consensus is that there are only minimal substantive differences among ATLAS.ti, MAX QDA, and NVivo. So, unless you have a specific set of advanced features that you need, it is almost certain that any of them will meet your needs.

For all practical purposes, the differences are largely at the level of "look and feel" -- i.e., how well you like any particular user interface. You can download free trial versions of all these programs, so I suggest you try out the ones that are most interesting to you.

You might also consider Dedoose which is a web-based program where you rent access by the month, rather than purchasing it.

Dear Prof. David L Morgan

After greetings and thanks a lot. I got the picture and I also had a look to your profile and your debates with other scientists was very useful for me.

All the best

Hi Peyman Falsafi, I use Genstat http://www.google.com/url?q=http://www.vsni.co.uk/software/genstat/&sa=U&ei=IKGSVMS4IYLgyQPX5IKADw&ved=0CAsQFjAA&sig2=BxNI8s7s_E1OmecLC-O3VQ&usg=AFQjCNEZc0jjChrg4crG_MS8vW_AXzM3YQ

It might be of use to you.

Thanks.

Dear Bravo!

Thank you for your contribution. I had a look to site which has introduced by you. But I think The software that you used is an appropriate software for quantitative data analyses. I couldn't find any relative point regarding qualitative research methodology and analyses.

Thanks again and good luck.  

There is also QDA Miner for qualitative research: http://provalisresearch.com/products/qualitative-data-analysis-software/

..and WordStat for content analysis and text mining: http://provalisresearch.com/products/content-analysis-software/

Dear Alejandro Martinez,

Thanks a lot because of your very useful contribution.

All the best
