Hi Antonella do you know what the type of acquisition is? That name isn't enough to know for sure, but it might be. And yes, you can run more than 1 recon at a time assuming you have enough ram on your machine. It won't go faster of course unless you have multiple cpus cheers Bruce On Fri,

Dear Bruce, I have two more questions for today, please: 1). Just to be sure that  I understood correct: for my  cortical thickness studies and also for a group studies analysis I will use only the data from the 3DAx_T1series which was converted to a .nii.gz file. Is this right? 2). If I want

I'm at my wits' end with what seems like it should be an easy question. I have a lot of volume labels that have been saved for a lot of brains. I want the Talairach coordinates corresponding to those points. It seems like mri_label2label should be able to do this, by putting in 'talairach' as th

Hi Antonella, no, you pick *one* file in each series (it doesn't matter which one, mri_convert will figure out the rest), and do something like: mri_convert 1.3.46.670589.11.17385.5.0.8952.2011042600464496394.dcm 3DAx_T1.nii.gz the only one(s) FreeSurfer will use are the 3D T1-weighted scan

Hi Jixin, mris_make_face_parcellation uses an icosahedral sampling, so you cannot use it with an arbitrary annotation, and the parcels in it will not correspond to the brain regions in any of the annots but rather will cut across boundaries. You could certainly use matlab for example to compil
