Reported by Peiyu Xu

[Tom Goddard]

The error says "MemoryError: not enough memory" after opening a session file

open F:\\\Onedrive\\\myPaper\\\Omicron\\\figure\\\fig5\\\compare_delta2.cxs

a PDB file and 4 PDB database entries

open 7cm4 7chf 7k90 6wps

Those 4 PDB entries load taking very little memory. The computer has 64 Gbytes. So it seems like the session file must be enormous to run out of memory. Maybe the session file contains some large maps that could be closed to stay within memory limits.
