Hello FSLers, I am rerunning template creation for VBM on Macaque monkeys. However my fslvbm_2_template contains an error in the "fslvbm2c.e70552" file. Here is the error message: (directories removed) "** ERROR (nifti_image_read): failed to find header file for '.../.../num_19_20110923_struc_GM_to_T' ** ERROR: nifti_image_open(.../.../num_19_20110923_struc_GM_to_T): bad header info ERROR: failed to open file .../.../19_20_test/num_19_20110923_struc_GM_to_T Cannot open volume .../.../19_20_test/num_19_20110923_struc_GM_to_T for reading! ** ERROR (nifti_image_read): failed to find header file for 'template_4D_GM' ** ERROR: nifti_image_open(template_4D_GM): bad header info ERROR: failed to open file template_4D_GM Cannot open volume template_4D_GM for reading! ** ERROR (nifti_image_read): failed to find header file for 'template_GM' ** ERROR: nifti_image_open(template_GM): bad header info ERROR: failed to open file template_GM ERROR: Could not open file" I find this error message particularly strange since the "num_19_20110923_struc_GM_to_T" .mat and .nii.gz files exist. This is the first file in my template_list (which I will upload) so for some reason the first call is failing and causing the others to fail as well. My template_list is the same as it was before when I had the template creation step working and is in my base fslvbm directory. Any hints or suggestions would be much appreciated, Daniel -- Daniel Cole University of Rochester Brain and Cognitive Sciences [log in to unmask]
