SURVIVOR didn't merge all SVs into output vcf

[pxchen110]

Hi Fritz,

I am trying to merge insertion variants from some vcfs and one of them is generated from DRAGEN.

Here is my SURVIVOR command: SURVIVOR merge input_ins_vcfs 1000 1 1 1 0 0 union6_ins_survivor.vcf (I change the last parameter to 0 for allowing all variants in input vcfs be merged in.)

However, I find that some variants from DRAGEN are not merged in and most of them don't have precise SVLEN information Here is an example of not merged in variant: 1 90370560 MantaINS:23588:0:0:0:3:0 T <INS> 510 PASS END=90370560;SVTYPE=INS;CIPOS=0,6;CIEND=0,6;HOMLEN=6;HOMSEQ=GGAGGT;LEFT_SVINSSEQ=GGAGGTGTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTGGAGGGGTTGGGGGTGGTGG;RIGHT_SVINSSEQ=CACCAGTATCCTTGCTTTTATAGTTCATTGCACCGCTTATTTTTTCTTTGCAGGCAAACGAATTTTTACATGGAATTTCTTGTTTTTGGCGGTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTGAGACGGAGTCTCGCTCTGTCGCCCAGGCTGGAGTGCAGTGGCGGGATCTCGGCTCACTGCAAGCTCCGCCTCCCGGGTTCACGCCATTCTCCTGCCTCAGCCTCCCAAGTAGCTAGGACTACAGGCGCCCGCCACTACGCCCGGCTATTTTTTGTAGTTTTAGTAGAGACGGGGTTTCACCGTTTTAGCCGGGATGGTCTCGATCTCCTGACCTCGTGATCCGCCCGCCTC GT:FT:GQ:PL:PR:SR 0/1:PASS:99:560,0,232:9,6:12,15

How could I change the parameter in order to merge all variants from input vcfs?

Thanks so much, Pinxuan

Hi,

I'm not an author but I'm running into the same problem.

Did you find a solution already?

Best regards

It does appear to be related to the lack of SVLEN in MantaINS calls. If you spoof a file that includes fake SVLEN values, the MantaINS calls will merge.
