I had the same problem, i.atcorr not work with LANDSAT-TM5 b1 and b2. My solution was changed the version of GRASS 6.4.1(in my cases) to 6.5.xx svn: i.atcorr works fine both b1 and b2.

Hi,

I had the same problem.
I don't know where your input data come from.
Now I know that it works if you use i.landsat.toar to calculate TOA
reflectance from DN images and then use these data as input files in
i.atcorr: you have also to use the flags -r (because of reflectance input)
and -f (because you need floating output).
I hope it will work!

Glad that it works in the improved i.atcorr version in GRASS 6.5.
Please try out the GRASS 6.5 binary snapshot:

I have just backported i.landsat.toar which is included now.
We'll backport the pending i.atcorr fixes asap to GRASS 6.4.
