Marking duplicates (filtered BAM)

Filtered out (samtools view -F 1804):

read unmapped (0x4)
not primary alignment (0x100)
read fails platform/vendor quality checks (0x200)
read is PCR or optical duplicate (0x400)

Mitochondrial reads are filtered out.

NRF (non redundant fraction)
PBC1 (PCR Bottleneck coefficient 1)
PBC2 (PCR Bottleneck coefficient 2)
PBC1 is the primary measure. Provisionally

0-0.5 is severe bottlenecking
0.5-0.8 is moderate bottlenecking
0.8-0.9 is mild bottlenecking
0.9-1.0 is no bottlenecking

Overlapping peaks

N1: Replicate 1 self-consistent overlapping peaks (comparing two pseudoreplicates generated by subsampling Rep1 reads)
N2: Replicate 2 self-consistent overlapping peaks (comparing two pseudoreplicates generated by subsampling Rep2 reads)
Nt: True Replicate consisten overlapping peaks (comparing true replicates Rep1 vs Rep2 )
Np: Pooled-pseudoreplicate consistent overlapping peaks (comparing two pseudoreplicates generated by subsampling pooled reads from Rep1 and Rep2 )
Self-consistency Ratio: max(N1,N2) / min (N1,N2)
Rescue Ratio: max(Np,Nt) / min (Np,Nt)
Reproducibility Test: If Self-consistency Ratio >2 AND Rescue Ratio > 2, then 'Fail' else 'Pass'

Enrichment

Strand cross-correlation measures

Performed on subsampled reads (15M)

	rep1
Reads	15000000
Est. Fragment Len.	230
Corr. Est. Fragment Len.	0.2529
Phantom Peak	35
Corr. Phantom Peak	0.2356
Argmin. Corr.	1500
Min. Corr.	0.1906
NSC	1.3269
RSC	1.3841

NOTE1: For SE datasets, reads from replicates are randomly subsampled.
NOTE2: For PE datasets, the first end of each read-pair is selected and the reads are then randomly subsampled.

Normalized strand cross-correlation coefficient (NSC) = col9 in outFile
Relative strand cross-correlation coefficient (RSC) = col10 in outFile
Estimated fragment length = col3 in outFile, take the top value

Fraction of reads in overlapping peaks

	rep1-pr
Fraction of Reads in Peak	0.4608

ppr: Overlapping peaks comparing pooled pseudo replicates
rep1-pr: Overlapping peaks comparing pseudoreplicates from replicate 1
rep2-pr: Overlapping peaks comparing pseudoreplicates from replicate 2
repi-repj: Overlapping peaks comparing true replicates (rep i vs. rep j)
