Hi Daniel,
Is it possible to get the original dicom data? You said the data were
already processed by Freesurfer when they got to you, so maybe whoever
gave them to you can point you to the whereabouts of the raw dicom files?

Hi Daniel,
you need to look at your original data (e.g. dicom files). You can
mri_info to tell you.

Hi. I was handed some data analyzed with freesurfer, and I would like to
know what is the exact resolution of the T1 mri, i.e. 1.25mm x 3mm x 2mm
for example.
Where can I look in the freesurfer folder to find out?
Thanks

One way to do it is, as you suggest, just put all the runs into the same
bold directory, then just use mc as registration. This works to some
extent. The main problem with it is that you can get fairly different B0
distortion between sessions because of the different head/body position

Dear fs-fast wizards,
doing monkey fMRI in Bremen (block desing so far) I run into the
problem that analysing the data from one session does not lead to well
defined activation maps. Therefore I would like to pool over several
sessions (always within one subject). Unfortunately I have did not
Hi Satra,
not usually, but in this case yes, since the changes are so large and

Does one need to recreate custom atlases when changing to a new release? And
if so does this process imply reprocessing all the subjects originally used

no, you want white matter to be close to 110 and gray matter to have a
sharp boundary and be considerably darker (e.g. 60)

What would be a good value for grey matter?
