In the code of SASA solvation energy a bug was introduced in the c31b1 to c31b2 transition, affecting versions c31b2, c32a1 and c32a2. When someone tries to simulate a sequence that does not contain any TRP or PHE or TYR (or whenever the nonbond explicit exclusion list is empty), one would get a segmentation fault. The error resides in the code source/misc/sasini.src. The problem can be solved by commenting two lines in this code:
line 512 :
IF (FNX .NE. 0) THEN
and the end of this if statement line 534:
We apologize for this. Simulations of systems with the aforementioned residues are not affected and should be correct.
