Re: [Freesurfer] Preprocessing functional MRI

Hi Zeke, Thank you so much ! It's working really well now. I have one more question- is there any way I can display labels (name of the areas) as well on the maps I see (using tksurfer command you suggested). Thanks Zeke once again. On Tue, Apr 26, 2016 at 4:44 PM, Z K wrote: > The "freadFloat

The "freadFloat: fread failed" is a warning, not an error, and can be ignored. The ces.nii.gz, cesvar.nii.gz, sig.nii.gz files are surface overlays stored in a "volume" format, so they have to be viewed on the surface. You can do with this with something like: $> tksurferfv fsaverage lh inf

thanks Dr. Fischl - it seems to match well so I will continue to use this method. It would be great if Ruopeng could eventually edit Freesurfer to allow for thresholding .labels too. On another note, is there a way to edit labels in Freeview in a similar manner to doing so in tksurfer?* From what

Martin, You need to provide more details for us to help you. What version of FreeSurfer? What exactly did you type in the command line as both your analysis and your call to freeview? If I were to take a wild guess, I would say you have the wrong surface loaded. That tutorial does the analysis on

Hello again, Somehow I figured out the error I had related to *.config. Now I am able to run successfully all the 8 steps for 1 subject. I can see all the files generated in a new folder i.e. ces.nii.gz, cesvar.nii.gz, sig.nii.gz etc. But when I try to display any of these files using FreeView (af

Hi Hassan we have answered you every time! Is is the total surface area of the white matter surface. It is just a single number per hemisphere so there is nothing to visualize Bruce On Tue, 26 Apr 2016, Hassan bakhshi wrote: > > Hello Bruce, > Sorry I'm in a hurry and its 3rd time I emailed.

Hi Lara, mri/orig.mgz should be there also in the longitudinal directories. If it is missing, more might be wrong. I would recommend rerunning those long runs from scratch. Best, Martin On 04/25/2016 07:07 PM, Lara Foland-Ross wrote: > Thank you Eugenio! This worked like a charm. > > Wondering

Hi Tilak I think you need to improve your data if that is an option. I couldn't see the gray/white boundary in either occipital or perirolandic cortex, so no parameters are going to help there cheers Bruce On Mon, 25 Apr 2016, Ramtilak Gattu wrote: Hey Bruce, Following up with the questio
