There is (sometimes) a segmentation fault in consed with the feature: consed -addNewReads I have fixed it. If you need it, contact me (David Gordon). There is an error message with navigate by snps on macosx. It says: consed error: contig3.cpp:849 Failed assertion 'pLocFrag1->nGetAlignStart() <= pLocFrag2->nGetAlignStart()' I have fixed it. If you need a fixed version, contact me.
