Dear All, I met a sort of strange situation. I did not get .hdr files but only .img files for some of my subjects after statistical analysis. I used the same script for statistical analysis, but for some subjects I can get regularly .hdr and .img files. I searched the spm mailing list but did not find the similar problems. It would be highly appreciated if someone could give me some hints! Thank you in advance! Our working environment is: SPM5 (spm_spm.m version 649), Matlab7.3.0 (R2006b), Linux.
