EasySpin forum

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,

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

It reads:
==================================================================

and there is no error after this.

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?

I am sorry. I missed the errors. It reads:
Error using eig
Out of memory. Type HELP MEMORY for your options.

Error in symm>symm_full (line 256)



Error in symm (line 118)



Error in p_symandgrid (line 14)



Error in pepper (line 566)



Error in pepper (line 159)



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

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

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.
