Re: [Freesurfer] contrast between two independent CTh maps?
Ah I see. Okay, will give this a try. Thank you Doug!

Re: [Freesurfer] contrast between two independent CTh maps?
Hi Doug, What do you mean by combining all the data (and how would you suggest we go about this?)? And also how does one do a two-group test? Thank you!

Re: [Freesurfer] contrast between two independent CTh maps?
when you ran mri_glmfit, you had to give it an input (eg, --y group1.mgh) with all the subjects from group 1. You would have a similar file for group2. You would then combine them into one file, eg mri_concat group1.mgh group2.mgh --o group1-and2.mgh you would then create a new FSGD file for both groups, then run mri_glmfit --y goup1-and2.mgh ...

Re: [Freesurfer] contrast between two independent CTh maps?
the easiest thing to do is to combine all the data together and do a two group test On 3/22/17 4:49 PM, Uquillas, Federico D'Oleire wrote: Dear FreeSurfer experts, I’ve been trying to find a way to get a map of the difference between two independent CTh association maps but can’t seem to find a solution.

[Freesurfer] contrast between two independent CTh maps?
Dear FreeSurfer experts, I’ve been trying to find a way to get a map of the difference between two independent CTh association maps but can’t seem to find a solution. I have two maps of independent groups (one is N=15, the other N=20) I would like to compare. Is there maybe a way to do a sig1.mgh – sig2.mgh and then visualize this? Not sure how to go about it. I’m basically trying to visualize what is left over after subtracting one map from the other (independent samples t-test of sorts). Thank you so much for any help you may be able to provide!
