Is there any way to get more information out from mri_ca_register than what is written in the logs? Lauge

mris_calc problem
by Dabbs (Kevin) 19 Sep '11

19 Sep '11

I have ran into a problem with mris_calc using Freesurfer 5.1 on Mac OS Leopard. When running long_mris_slopes I am getting this error; ERROR 1 : mris_calc compute sym. pct. change (spc) problem? It seems to running properly until it hits; mris_calc -o /Volumes/larry/cluster_results/1007base3/surf/lh.long.thickness-spc.fwhm0.mgh ./tmp-1007base3_lh_thickness_PENQ8v/beta1.mgh div ./tmp-1007base3_lh_thickness_PENQ8v/beta0.mgh The ./tmp files do exist whern mris_calc is called. I have seen on the Wiki that a fixed version of mris_calc is available for Centos. If you think I could be running into the same problem, is a fix available for Leopard? Thanks, Kevin Department of Neurology University of Wisconsin-Madison

Is this normal when importing the annotations in tksurfer?
by Chen, Xu 19 Sep '11

19 Sep '11

Hi, Just installed FreeSurfer 5.1 ( stable ) to my 64 bit Ubuntu 10.04 LTS (kernel 2.6.32-33). Playing with it to test the Freesurfer installation. Everything seems OK when running "tkmedit". However, a msg shown below pops up when I was trying to view cortical parcellation labels in tksurfer as instructed in the webpage of "testingfreesurfer". "...... Found embedded color table in annotation. 8600 vertices did not have an annotation!" What does this message implicate? Could it be attributed to the data problem (e.g. the inconsistency of vertices between the annotation & surface ) or my computer system? Is it normal to get it?

Re: [Freesurfer] ICV differences from version 5.0 to 5.1
by Ed Gronenschild 19 Sep '11

19 Sep '11

Jon, The reason is that already in one step earlier in the pipeline, the nu-correct stage, a difference arises. See thread on "Differences in nu.mgz between v5.0.0 and v5.1.0" Cheers, Ed > Hi, > > We have noticed differences in Talairach registration (and > therefore ICV estimates) in some of our subjects from version 5.0 > to version 5.1.

recon-all steps necessary to get aseg.nii
by Jeff Eriksen 19 Sep '11

19 Sep '11

I would like to run FreeSurfer just up to the point it creates the aseg file, and no further. I believe this would be steps 1 through 11. Is there any way other than making a copy of the recon-all script and removing everything after step 11. Not sure I know exactly where this is. -Jeff
