[GRASS-user] r.watershed problems in wingrass

[Gerald Nelson]

I tried it without the @ sign with no success; ie, the same problems. Where
I am getting success is if I use the disk for paging. I suspect some kind of
memory management issue having to do with Windows. I'm copying this email to
the dev list in case someone there has a fix.

Regards,
Jerry

I wrote r.watershed before GRASS allowed the use of @ symbols. (Or, if GRASS
did, I didn't know about them then.) It is possible that something in the
init.c file is wrong. Does the problem still exist when you add
"india_basic" to the list of mapsets and run r.watershed without the
"@india_basic"?

I'm using wingrass63RC4. I am trying to find watersheds in India. I run

"r.watershed elevation=IndiaElev at india_basic threshold=100
basin=IndiaBasins"

The result after a couple of seconds is 

"category information for [IndiaBasins] in [india_basic] missing or invalid"

It's as if grass is trying to read the new map before it creates it.
