Comment: C: How To Find The Locations Of A Short Specific Sequence In A Genome With 1 Or 2 M
... Hi, I tried your method to find the genomic location of a DNA sequence in the hg19 genome, and I ran the following command - `bwa aln -n 4 -o 0 -k 4 -N hg19.fasta testmotif.fq > out.sai` But the out.sai file seemed to only have illegible stuff in it - `SAI ...

But, when I try to do HiC analysis using them, a code in the pipeline that is supposed to merge the 2 bam files gives the error - *## Merging forward and reverse tags ... Forward and reverse reads not paired. Check ...

Extract R1 and R2 bam files from merged bam file
... Hi, I started with R1 and R2 fastq files, and using a pipeline ([https://github.com/ArimaGenomics/mapping_pipeline/blob/master/Arima_Mapping_UserGuide.pdf][1]), I combined them to give a merged bam file (it also does other things like filtering for mapping quality, adding read groups and remove PCR ...

Comment: C: Why does this samtools command work?
... Got it, so basically the perl script is doing both - merging the 2 bam files, and simultaneously filtering based on map quality. So, if I had to get rid of the merging of the bam files, and still filter the 2 (R1 and R2) bam files, then I can bypass this perl script altogether and do the filtering u ...

Answer: A: Insillico dual restriction enzyme reference genome digestion.
... Another good option is a utility called digest_genome(.py) that comes with HicPro. It can digest the reference genome by the provided restriction enzymes(s) and generate a BED file with the list of restriction fragments after digestion. You can specify multiple restriction enzymes too. [here is the ...

Can we look at interactions between host genome and pathogen genome from Hi-C data?
... I have Hi-C data from human cells that were infected with a virus. It's possible that the virus genome interacts with the host (human) genome. Is it possible to find out these interactions from this Hi-C data? (maybe by somehow finding reads that, say, did not match to the human genome, or those th ...
