tms data and Grass

Good Evening,

I'm interested to know if there is a tutorial that will go through importing
TMS data from CDROM into grass. I need to know how to use i.rectify,i.group
and i.points . I have a TMS image file and a lat and lon file.

I'm alittle confused as to how Grass will reference the Lat Lons with the
Image. Basically I can view the image in Grass, but the coordinates from
g.region will mean little in terms of pin pointing say site locations .

Anyway as I said a tutorial of some sort to do this would be helpful

Thank you

Jeremy Dunn
