[GRASS-user] G_calloc error using r.in.xyz

I’m using r.in.xyz on a simple xyz point cloud. I’m operating on 64 bit Windows 7 with 4 GB RAM and 1.7GHz i5 processor. I am running GRASS 6.4 from the MSYS command line and I am using this tutorial as a templete.

My data is simple xyz from a comma seperated text file. I can import this txt file and use GRASS to convert it to .las format, I have set g.region and now I am working to import with r.in.xyz. The las2txt portion is working and I can see a comma delineated text file as output. When I attempt to run it with r.in.xyz using the following command

r.in.xyz in=FILENAME.txt fs=, out=FILENAME_RAST

I receive the error

ERROR: G_calloc: unable to allocate 1253898072 * 4 bytes at main.c:431

Looking up documentation I thought implementing the percent option as follows would help the problem

r.in.xyz in=FILENAME.txt fs=, percent =50 out=FILENAME_RAST

However using percentage values all the way down to 1 I received the same error, however the number multiplied by 4 bytes decreased to 78563304

Has anyone else encountered this error? Is it a command line error or insufficient processor capability?

Thanks!
