Hi, since I wanted to track down this issue I tried
t_coffee -aln sproteases_small.cw_aln sproteases_small.muscle sproteases_small.tc_aln -outfile combined_aln.aln on my usual testing machine. However, when running on sid I get the reported error: ************************************************************************************************* * FULL TRACE BACK PID: 23180 23197 -- ERROR: COREDUMP: T-COFFEE Version_12.00.7fb08c2 (2018-12-11 09:27:12 - Revision 7fb08c2 - Build 211) ************************************************************************************************* Unfortunately just starting plainly under gdb does not change anything. Any idea how to track down this besides adding debugging printf into the code? Kind regards Andreas. -- http://fam-tille.de
