I am using ONT long reads to try and find breakpoints for a large putative chromosomal inversion in our study organism (salmon). My end goal is to generate a dotplot from my .paf file to give a rough sense of where breakpoints are.
I used the command
minimap2 -x ava-ont $GENOME $READS/barcode09.fastq.gz > barcode09.OgorEvenAss.approx-mapping.paf
to generate a .paf file between between the species assembly (a fasta file) and our raw reads ( a fastq file).
However the qname in my .paf file is the parent_read_id from the fastq file.
For example (first five lines of my .paf):
74baa321-d50a-48f8-a8b8-dbe2a90b3708 484 103 436 + NC_060193.1 60884844 44630007 44630343 262 336 0 tp:A:S cm:i:55 s1:i:261 dv:f:0.0239 rl:i:202 40627972-bcb1-47d4-aad4-4f1a8c2f2535 3205 93 3118 - NC_060196.1 66433064 36518740 36521756 2167 3050 0 tp:A:S cm:i:521 s1:i:2154 dv:f:0.0294 rl:i:681 40627972-bcb1-47d4-aad4-4f1a8c2f2535 3205 1370 1812 + NC_060194.1 52623370 39483873 39484307 122 445 0 tp:A:S cm:i:14 s1:i:118 dv:f:0.1173 rl:i:681 40627972-bcb1-47d4-aad4-4f1a8c2f2535 3205 1370 1812 - NC_060195.1 72202100 65678923 65679365 122 452 0 tp:A:S cm:i:15 s1:i:117 dv:f:0.1132 rl:i:681
I also attempted the same approach with from my SAM files using the command (and received essentially the same results):
paftools.js sam2paf barcode06.aln.sam > barcode06.aln.paf
Is the only way to get a .paf file with chromsome or contig names in the qname and tname columns to use an assembled .fasta file?
Yes
