Hello,
Is it possible that you typed something like:
fslmaths 1.nii.gz -add 2 1_2_added.nii.gz
rather than
fslmaths 1.nii.gz -add 2.nii.gz 1_2_added.nii.gz
?
As a check, can you rename your files to something with a non-numeric basename, e.g. image1.nii.gz, image2.nii.gz and repeat the fslmaths call?
Kind Regards
Matthew
