Thanks very much Frans, I saw the option for linear gamma in the MTFMapper GUI, but from the check box text I assumed it only applied to 8 bit images. The image actually comes from what is essentially an industrial camera, so the source image doesn't have any color profile information. It must get added somewhere down the line, possibly when I cropped it in Gimp. I've now tried saving it without a color profile, but PNG seems surprisingly stubborn in hanging onto gamma (which always seems to be 0.4545)....

Hi Frans, I’m trying out MTFMapper on a single ROI image crop (attached) and getting results that differ considerably from what I obtain with sfrmat. The MTF estimates at Nyquist (90.91 lp/mm) are: MTFMapper: ~30% sfrmat5: ~19% sfrmat3: ~21% I also tried a couple of tools which gave different results again: Mitre SFR 1.4.2: ~24% ImageJ: ~10% The target is approximately at best focus (~2m distant). There is noticeable FPN, and the target was just taped (not glued) onto a board, so you can see some...

Hi Robert, The bash command set is a superset of the sh command set, and I believe it is backwards compatible with sh. Tcsh doesn't use the same syntax or keywords as bash or sh (it is a superset of csh, the other early Unix shell). Below are equivalent bash and tcsh commands. bash/sh: bar="hello" export foo="there" tcsh/csh: set bar = "hello" setenv foo "there" Both of the AppleScript scripts I attached in my bug report should work no matter what the user's default shell is (although I've only tested...

Hi Robert, I replied to your coment in email (I'm on the maxima bugs mailing list), I'm new to this so not sure if my reply will show up here. In case, it doesn't I've included it below. Apologies if this is redundant. The bash command set is a superset of the sh command set, and I believe it is backwards compatible with sh. Tcsh doesn't use the same syntax or keywords as bash or sh (it is a superset of csh, the other early Unix shell). Below are equivalent bash and tcsh commands. bash/sh: bar="hello"...
