Dear Borys,

Indeed Slapaf module was not well tested for MEP. There are also some other 
restrictions when using Slapaf which maybe not properly indicated in the 
manual. Could you provide an example input which does not work as expected? 
This will help us in fixing the problem. Also, the manual will be updated.

Best wishes,
