Missing key SEQ for <INS>

[brentp]

Hi, I am trying to use paragraph to genotype manta calls. I get this error:

  Exception: Missing key SEQ for <INS> at 1:145235303; 

and that variant is indeed:

1       145235303       .       T       <INS>   0       .       END=145235303;SVTYPE=INS;CIPOS=0,14;CIEND=0,14;HOMLEN=14;HOMSEQ=GGAT
ATCAGGTTTT;LEFT_SVINSSEQ=GGATATCAGGTTTTCCTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTAAAGTGTGTGGGTCTTT;RIGHT_SVINSSEQ=GACCTCGTGATCCGCCTGCCTCGG
CCTCCCAAAGTGCTGGGATTACAGGCGTGAGCCACCGCGCCCGGCC

so it has left and right, but not SEQ. Is there something I can do to have paragraph genotype these? For example setting SEQ = LEFT_SEQ + N*100 + RIGHT_SEQ ?

Bump. I'm wondering if setting SEQ = LEFT_SVINSSEQ + N*100 + RIGHT_SVINSSEQ will work with the machinery in paragraph. I can preprocess the VCF to do this but want some idea that it does not violate some internal assumptions.

Is there also some way to genotype BND elements?

thanks!

what is a homeseq in your info

[atongsa]

vim paragraph/lib/python3/grm/vcfgraph/vcfgraph.py

edit this block to your insert SEQ is ok

        if alt == "<INS>":

When the full insertion sequence cannot be assembled, Manta will report the sequence near breakpoints instead. Paragraph only uses sequences around breakpoints for genotyping, so @brentp solution should work.

Nice hack! vcf.info["LEFT_SVINSSEQ"] + ('N' * 200) + vcf.info["RIGHT_SVINSSEQ"]

will throw an error though, as vcf.info["LEFT_SVINSSEQ"] is returned as a tuple ("ACC...T",), so vcf.info["LEFT_SVINSSEQ"][0] is what will be needed to get to the seq.

Indeed. I am accumulating all the changes here: https://github.com/Illumina/paragraph/compare/master...brentp:bp-dev
