I want to convert a density map (mrc) to structure factor (mtz) using the script in the EM_fitting_tools, while I faced a problem, I have no idea about it. 

the script mrc2mtz mainly calls the two programs: mapmask and sfall. the mapmask succeeded to convert the map to a intermediate map "tmp.map", but sfall failed to convert it to structure factor. Here is the output of the program sfall.

it seems that sfall failed to open the file because of no such file or directory, also did not open the library file.
