i want to convert the ".annot" files to nifti. When i used "mri_label2vol", I used this command
mri_label2vol --subject fsaverage --annot $FREESURFER_HOME/subjects/fsaverage/surf/lh.ic3.annot --o test.img --hemi lh --regheader $FREESURFER_HOME/subjects/fsaverage/mri/brain.mgz --temp $FREESURFER_HOME/subjects/fsaverage/mri/brain.mgz
But the error is:
Number of labels: 0 Annot File: /usr/local/freesurfer/subjects/fsaverage/surf/lh.ic3.annot Template Volume: /usr/local/freesurfer/subjects/fsaverage/mri/brain.mgz Outut Volume: test.img Registration File: (null) Fill Threshold: 0 Label Vox Vol: 1 ProjType: (null) ProjTypeId: 0 ProjStart: 0 ProjStop: 0 ProjDelta: 0.1 Subject: fsaverage Hemi: lh UseNewASeg2Vol: 1 DoLabelStatVol 0 $Id: mri_label2vol.c,v 1.32 2009/10/22 23:35:53 greve Exp $ Template RAS-to-Vox: -------- -1.000 0.000 0.000 128.000; -0.000 -0.000 -1.000 128.000; -0.000 1.000 -0.000 128.000; 0.000 0.000 0.000 1.000; Template Voxel Volume: 1 nHits Thresh: 0 Computing registration based on header RegMat: -------- 1.000 0.000 0.000 0.000; 0.000 1.000 0.000 0.000; 0.000 0.000 1.000 0.000; 0.000 0.000 0.000 1.000; Label RAS-to-Vox: -------- -1.000 0.000 0.000 128.000; 0.000 0.000 -1.000 128.000; 0.000 1.000 0.000 128.000; 0.000 0.000 0.000 1.000; INFO: loading surface /usr/local/freesurfer/subjects/fsaverage/surf/lh.white nvertices = 163842 Reading thickness /usr/local/freesurfer/subjects/fsaverage/surf/lh.thickness Loading annotations from /usr/local/freesurfer/subjects/fsaverage/surf/lh.ic3.annot reading colortable from annotation file... colortable with 642 entries read (originally /usr/local/freesurfer/lib/bem/ic3.tri) annotidmax = 640 Allocating Hit Volume (-2147483648) voxels MRIalloc(256, 256, 256): could not allocate 131072 bytes for 22494th slice

Does anyone know, why is that happening and how can I correct it?
