Total Volumes question

Submitted by MCube78 on Thu, 09/22/2011 - 03:31

Hi I am looking at using DPARSF/REST for a dataset, but different subjects/sessions have different total volume numbers. Is that a problem?

cheers

Hi!
Thanks for your interests in our work.

If you have different total volume numbers for different subjects, could you discard some time points to make them equal?

E.G. Keep the first 150 volumes, is it feasible?

If you perform a group comparison between two groups with different volumes, then it is difficult to interpret the difference is caused by disease or just the scanning.

Best wishes!

Thank you for the suggestion. For now I have created different folders with different TRs so I can run the analysis of each set, but I will keep your suggestion in mind!

thank you
