Dear all,
Have I understood correctly that the slice delay of each slice is not
needed when performing slice time correction with preprocess-sess?
I am processing an open OASIS fMRI dataset. The dataset has fMRI data in
nifti format and JSON files

Dear Freesurfer experts,
Could you please let me know how to normalize fMRI data without upsampling
the original voxel size from 5 x 5 x 7 mm to 2 x 2 x 2 mm? I have tried
this as follows:
1. Register functional (data.nii) to anatomical matrix
Dear Freesurfer experts,
I have used fslregister to register fMRI data to anatomical data.
However, now I would like to register all fMRI runs to the fMRI run that I
have registered to the anatomical data.
Could someone please let me know how to get a register.dat file between
fMRI runs?
Many
Dear Freesurfer experts,
I would like to extract time courses of certain brain structures from the
stc file in Matlab. Could someone please let me know how I can determine
the lables of 10242 verices of my stc file? Or is there some matlab
function that gives the time course of a barin structure.

Could someone please let me know what is the meaning of the arguments -iid,
-ijd, -ikd, -iis, -ijs, and -iks of mri_covert?

Dear Freesurfer experts,
I have tried to mask fMRI data with grey matter mask as follows:
mri_mask fmri_data.mgh ribbon.mgz masked_fmri.mgz
However, I am getting an error " dimension mismatch between source and
mask".
Could someone please let me know how to solve this problem?
Best,
Maria
