[GRASS-user] Raster maps not found

GRASS GRASS user

Hi there,

I’ve just moved a lot of data that we’re working on onto a NAS server so that two computers could chew up the same data simultaneously. After moving everything onto the server, I copied the relevant data to the local hard drive of the computer that should be doing the analysis. On the other computer it seems to work fine, although the data was originally produced on that computer so perhaps that’s part of the problem. Anyway, when I try to start r.sun for example on the other computer, GRASS complains that it can’t find the data. The error says:

Unable to find ‘/home/lee/Documents/GRASS_Data/Hayward/StudyAreaTopography/cell_misc/horizon_143/f_format’
Unable to open raster map horizon143@StudyAreaTopography

It repeats that message for every single raster I try to call up.

I’m also not able to display any rasters. I know that they exist on the other computer and I can view them, but when I try to do that on the second computer GRASS doesn’t complain about loading them and displaying them… But absolutely nothing happens.

Any idea why this is going on? I copied the stuff straight over without modifying it in any way.

Regards,
Daniel

Does that file exist? Is it readable by the user running GRASS?

Copying the stuff "straight over" doesn't mean that it doesn't get
modified. Particularly if you're using a FAT/NTFS-based NAS with a
Unix system, as filename case and/or permissions may be lost in the
copy.
