Dear Markus

 

a) I run the "probtrackx" through the GUI window. I first set the BEDPOSTX directory, then I set the X Y Z coordinate to one single voxel I am interested in, then I "GO".

 

b) I set the name of input directory for "bedpostx" step is "bedpostx", so after it is done, the output directory is "bedpostx.bedpostX". When doing "ls bedpostx.bedpostX", it shows the following ifnormation:

bvals                  mean_f2samples.nii.gz    merged_ph1samples.nii.gz
bvecs                  mean_ph1samples.nii.gz   merged_ph2samples.nii.gz
commands.txt           mean_ph2samples.nii.gz   merged_th1samples.nii.gz
dyads1.nii.gz          mean_th1samples.nii.gz   merged_th2samples.nii.gz
dyads2.nii.gz          mean_th2samples.nii.gz   monitor
logs                   merged_f1samples.nii.gz  nodif_brain_mask.nii.gz
mean_f1samples.nii.gz  merged_f2samples.nii.gz  xfms

 

Thank you very much for your help!

Best

Yonghui

Hi! In order to help, we need to know more. Can you post a) the probtrackx command you run? b) what you get when doing "ls <your_bedpostx.bedpost>" It is most likely that there is a file missing or has the wrong name or the wrong path... Hth, Markus 2009/11/3 YonghuiLi <[log in to unmask]> Dear FSL, I run into some troubles while try to do the probtrackx on single voxel. The "eddycurrent" and "bedpostx" steps are completed. Then I continued the "probtrackx" by enter the coordinate of a single seed voxel. Then "GO". But it stopped very soon, showing an error message: "Errors: Image Exception: #99 :: Out of memory  terminate called after throwing an instance of 'RBD_COMMON::BaseException' Then the whole procedure stopped. Your help to my situation here will be highly appreciated. All the bests! Sincerely, Yonghui Li Email: [log in to unmask] 2009-11-03 -- Dr. med.
