Dear Tarek

        I've been bringing a lot of tm images into grass lately and I've
found it easiest just to copy the raw data file into your cell directory then
write a header in cellhd. will give range, histogram, and a 
cats file. If you have ERMapper, seperate the band interweave into 
seperate files. If you store the ER headers with the files in cell, ER 
and GRASS will both be able to access them without any further conversion.
Good luck.
