Hi, I am having some trouble converting 2 images from analyze to nii.gz format for use in TBSS. The files are getting cropped (about the top 10 slices) after conversion, and I get error messages about "Missing header/image files" and "Failed to load base image. Command line processing aborted." when trying to view in fslview and the following when using fslmaths: ++ WARNING: nifti_read_buffer(FA.nii.gz): data bytes needed = 3483864 data bytes input = 2624584 number missing = 859280 (set to 0) I ran fslhd and got the same output except for a difference in the vox_offset which was 0 on the analyze file and 352 on the nifti_gz file. However, this was also true for files that did not have trouble with the conversion. We are using regular characters in the file names-no spaces. Your help is appreciated! Thanks, Laura
