Support bam's as input to treeshop

[rcurrie]

@hbeale I've added basic bam to fastq conversion:

                    docker run --rm \
                      -v /mnt/samples:/samples \
                      quay.io/ucsc_cgl/samtools:1.5--98b58ba05641ee98fa98414ed28b53ac3048bc09 \
                      fastq -1 /samples/{0}.R1.fq.gz -2 /samples/{0}.R2.fq.gz /samples/{1}

(Same method as used in cgl-rnaseq)

Treeshop will make the conversion and copy the resulting fastq's back to derived under archive for posterity and then proceed with rnaseq etc....

[hbeale]

Cool. Has it worked?

Hmmm...output isn't matching but maybe its my fastq -> bam:

docker run -it --rm -v pwd/samples:/data broadinstitute/picard FastqToSam F1=/data/TEST_R1.fastq.gz F2=/data/TEST_R2.fastq.gz O=/data/TEST.bam SM=TEST001 RG=rg0000

converting this bam back to fastq via samtools, then through rnaseq, then umend and the readDist.txt differs.

@hbeale is it reasonable that these should be identical:

fastqs -> rnaseq sorted.bam output -> umend

fastqs -> picard bam -> samtools to fastq -> rnaseq sorted.bam -> umend

?

converted bam in the develop branch:

https://github.com/UCSC-Treehouse/pipelines/tree/develop/samples

[hbeale]

when you say " samtools to fastq -> umend", does "fastq -> umend" represent the rna-seq pipeline (using STAR) and then the bam-umend-qc process? yes, i'd expect them to be identical, but i don't know where to go if they're not. I'd approach is by comparing the outputs of these two approaches: bam -> btfv9 -> groomed fq -> umend bam -> samtools to fastq -> un-groomed fq -> umend

Verified via notebook that round trip fastq -> bam -> fastq matches at the read level. Also verified that bam -> fastq generates the exact same secondary output as the original fastq's. Samtools in cgl docker used for the actual conversion. Will run a CHOC sample to finalize this improvement.
