Segmentation fault when trying to extract core genome alingment

[teddyaroca]

When I run:
stripSubsetLCBs full_aln.xmfa full_aln.xmfa.bbcols core_aln.xmfa 500 4

I always get this error:
Exception FileNotOpened thrown from Unknown() in gnFileSource.cpp 67 Called by Unknown() Read 41960 backbone entries seq_count is: 0 output_ivs.size() 3049 Segmentation fault
