Alignment of 2 LongAminoAcidSeq with AffineGapScoreModel from docs goes out of bounds

[kool7d]

Affine alignment is not working, but simple edit distance works.

strucseq = "KVFGRCELAAAMKRHGLDNYRGYSLGNWVCAAKFESNFNTQATNRNTDGSTDYGILQINSRWWCNDGRTPGSRNLCNIPCSALLSSDITASVNCAKKIVSDGNGMNAWVAWRNRCKGTDVQAWIRGCRL"

msaseq = "KIFERCEFARTLKRNGMGGYHGIRLADWVCLARWESSYNTKATNYNSKSTDYGIFQINSRYWCNDGKTPGAVNACGISCNVLLQDDITQAIACAKRVVDPQGIRAWVAWKKHCEQDLTQYQGC"

Expected Behavior

Something like

costmodel = CostModel(match=0, mismatch=1, insertion=1, deletion=1)
alignment = pairalign(EditDistance(), strucseq, msaseq, costmodel)

provides

PairwiseAlignmentResult{Int64, LongAminoAcidSeq, LongAminoAcidSeq}:

Current Behavior

costmodel = AffineGapScoreModel(BLOSUM62, gap_open=-10, gap_extend=-1)
alignment = pairalign(GlobalAlignment(), strucseq, msaseq, costmodel)

gives

I can't reproduce this. @kool7d Can you verify that you can reproduce it?
Based on the stacktrace, I suspect this is a duplicate of #46 .
