Re: [Freesurfer] Memory problem

Hi Mia, try looking at the lh.orig.nofix surface. There may be a huge defect (like the entire cerebellum is attached). You can run tkmedit MG58_SurferOutput_postop orig.mgz lh.orig.nofix Note that you will get a few error messages when loading the orig.nofix surface. These can be ignored doug

There is an automasking done in mri_glmfit. For each voxel, it looks through all the inputs. If one of the inputs is 0, then that voxel is masked out. If you have data where this is expected (eg, VBM-like data), then you can add --no-prune. If this is not expected, then look through your data

They must be in a single folder and the $SUBJECTS_DIR env variable must be set to that folder. If you know a little unix, you can set up folders with symbolic links to subjects' true directories. doug On 01/23/2013 02:58 PM, Nucleos P wrote: > Thank you for your help Doug! > I was trying to s

Hi Nick, Could you clarify this? So if we re-run a subject in 5.1 (say after doing some edits), we would then need to run it again a third time in order to maintain consistency? Thanks. -Derin On Jan 22, 2013, at 2:17 PM, Nick Schmansky wrote: > also there is an issue in v5.1 where the seco

[Freesurfer] Downsampling/decimating overlays (not surfaces)

2013-01-23 Thread Nicola Toschi
Hello list, is there a quick way to decimate an overlay /while respecting surface geomery)? I am looking to downsample by about a factor 100. Alternatively, I know I can use mris_decimate to downsample a surface, but I would have to project my highres overlays onto the downsampled surface (w

hi, what we do with MEG in the MNE package is indeed store downsampled overlays (that actually have a temporal dimension). More specifically we store the values e.g. only at the vertices of the ico5 subdivision and store the ico 5 vertex indices and overlay values. Then to display them on the high
