Outputs
Description
Converts values in a COR volume to a label. The program searches the COR volume in directory 'cordir' for values equal to 'labelid'. The xyz values for each point are then computed assuming 1 mm^3 voxels and that xyz=0 at the center of the volume. The xyz values are then stored in 'labelfile' in the label file format; the vertex values are set to zero as is the statistic value. While this program can be used with any COR volume, it was designed to convert parcellation volumes, which happen to be stored in COR format. See tkmedit for more information on parcellations. The labelid must be within the range of 0 to 255. The label volume in mm^3 can be written to the argument of --v.
Examples
Example 1
mri_cor2label --c /space/final/frontier/myparcellation
- --id 57 --l /home/brainmapper/spattemp/57.label
This will load the COR volume found in the directory /space/final/frontier/myparcellation and then search the volume for values equaling 57. The results are stored in 57.label in the directory /home/brainmapper/spattemp, which must exist prior to execution.
Example 2
Bugs
- If the name of the label does not include a forward slash (ie, '/') then the program will attempt to put the label files in $SUBJECTS_DIR/subject/label. So, if you want the labels to go into the current directory, make sure to put a './' in front of the label.
