I am using grass GIS software for converting and I am using OSGeo4W shell that is used linux environment. For Converting airtemperature in kelvin to Deg C is used " r.mapcalc, but I have this error " command not found ". It means modules doesn't work. I am not sure but I think my bash linux has a problem. This data is used as input for the pySEBAL algorithm. Can anyone help me?

My interest is the magnetic properties of these systems, using ORCA software under Linux environment.

thank for all.

Dear college: I'm looking forward to find somebody who is having a powerful Nvida GPU for parallel

GPGPU simulations in the context of GA's. I need to access remotely to a machine for running my own numerical C-Cuda programs. I work in the Linux environment. I offer to publish the resulting research work together with who wants to collaborate with me. Please, send a private message if you are interested.

I've been using the IDL software in Windows environment for many years . Recently, I encountered a problem and I could not solve it. Please guide if possible. The problem is that I've written a code in IDL that needs to read data with test.dat format from the another machine with linux environment of course two these machine are network. Unfortunately, when calling the open command the following error message appears:

“The system cannot find the path specified.”

and the open command is :

data_path ='root/home/mydirectory/'

openr,1, data_path+test+"."+"dat"

The code source is in the Windows and the the test.dat is in another machine with linux. I think the path given is wrong, but I do not know how to connect the two machine or change the path.
