unable to run "pepper" on R2014_a

Post by archana.tiwari »

I tried running the example file viz. eespins.m, and found "Error in eespins (line 16) pepper(Sys,Exp);". When I checked the magnetization data curves (curry) and others (chili etc.), they are all compiling fine on Matlab (on macOS 10.13.2). Please suggest how to proceed with the "pepper"-based files. I need to fit some cw-EPR data. Thanks in advance.

Best,
Archana

Please post the output of calling easyspin and the full error message you get.

So the eespins example works without error? If not, post the full error message printed to the command window.

When I run "eespins" the Matlab command window reads:

Error in eespins (line 16)
pepper(Sys,Exp);

This appears to be only the end of the error message. What is printed prior to that?

There is not enough memory to run the simulation. Try to use sparse matrices to reduce required memory space:

Code: Select all

Opt.Sparse=1;
pepper(Sys,Exp,Opt);

Opt.Sparse=1 is also of no help. The same error persists. Please suggest.

Try to use detailed output with Opt.Verbosity=2 and place the output here. This should localize the error. Also You may try to type memory in the command window but I'm afraid it's unsupported for unix-based systems.
