Dear Bruce,

Many thanks for your reply and your help.

Can you please give me an advise on how I can do a comparison between two groups for my FA data or in other words for FA group analysis since from the significant map I can only find the p values how can I see if there is an increase or decrease of the FA values for controls versus patients?

Many thanks, Antonella

Dear FS team,

Can use my results from the mri_cvs_register to do a non_FA group analysis, more exactly I am interested on the mean diffusivity (adc.nii from dt_recon).

Since from the significant map I can only find the p values how can I see if there is an increase or decrease of the FA values or how can I do an FA comparison between two groups?

Thank you very much for your time and help. Antonella
