Re: [Freesurfer] Functional data analysis in qdec

I don't think so, but maybe Martin or Nick know otherwise. Otherwise, 
you'll have to use mri_glmfit

 Dear FS experts,


 I'm wondering whether is possible to perform vertex analyses on pet

 my functional data converted to surfaces.
 Qdec 1.5 says that the functional design is not yet implemented. So, 
 I'm wondering is there is a way to get my pet data into qdec?


 I have tried in every single subject: mris_preproc --s subj001 --hemi 
 ?h --meas subjPetSurf.mgh --target myAVGsubj --out 
 ?h.thickness.myAVGsubj.mgh
 And then just smooth the resulting surface, so the qdec might use my 
 functional data as if it were the thickness. But I'm not sure if it is 
 a good solution or I'm doing something wrong, because the results look 
 so different from those on the command line group analyses.


 Any guidance here will be so appreciated!


 Many thanks in advanced,
 Gabriel

[Freesurfer] Functional data analysis in qdec

2015-03-11 Thread Gabriel Gonzalez Escamilla
Dear FS experts,


I'm wondering whether is possible to perform vertex analyses on pet data using 
qdec, I'm running FS v5.3.0 under ubuntu 12.04. I have all my functional data 
converted to surfaces. 
Qdec 1.5 says that the functional design is not yet implemented. So, I'm 
wondering is there is a way to get my pet data into qdec?


I have tried in every single subject: mris_preproc --s subj001 --hemi ?h --meas
