I want to calculate the interface area of several proteins using pdb files consisting of two chains, for instance, 1P9U_AG.pdb, having the chains A and G. However, every time I use the naccess to do so from the terminal, it gives output as follows
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:

6 0x7fba08b2f0b2
7 0x55835f8c821d
8 0xffffffffffffffff
Segmentation fault (core dumped)
Though this does create the expected .rsa, .asa, and log files, they either don't have any relevant data when I open them or a message like the one below pops up
"Unexpected error: Invalid byte sequence in conversion input."
The program works perfectly fine with pdb files comprising of individual chains though. I would be really grateful if someone offers a solution to resolve this issue.
