Splitting human bam file into fixed regions

Question

[irfanwustl]

I have a bam file for the human whole genome. I want to split the bam file into multiple bam files, each having a fixed number of bases. How can I do this efficiently? I know I can generate a bed file with fixed regions, then run samtools view. Any other better way?

I want to split the bam file into multiple bam

why would you want to do this. What is the "next step" ?

I would recommend talking about the problem you think the above is a solution to.
