C: reads alignment statistics
... Thanks for the hints on countBam. However, I still cannot get the number of uniquely mapped reads.
I thought the following should return number of multiple mapped reads. However, it returns 0 when I know there are multiple mapped reads. bowtie2 shows ~14 millions reads
file='input.bam'

Is there an R package that can calculate alignment statistics from bam/sam files? By alignment statistics I mean number of reads, number of reads uniquely mapped, number of reads mapped to multiple locations.

C: ChIPQC plots for input samples
... Tom, thank you so much for your quick reply.
Faceting by tissue and color by factor gets me closer. However, it still do not plot the input. It's probably because I didn't specify the samples sheet correctly. So, in my samples sheet, I previously only listed my ChIP samples and in bamControls the p ...
