What is the difference between the manta disease model (--tumorBam) and germline model (--bam)? i.e, different calling algorithms, different filtering criteria? Is there some detailed documentation on that?

Thanks

Have you checked the method overview or the methods PDF in the repo? Manta can run on germline only, tumor only, and paired tumor/normal subtractions. I believe it's methods PDF explains most of the details.

There's also the preprint on the biorXiv, which has a pretty extensive supplement.

The short answer is that the germline model assumes a diploid sample with corresponding allele frequencies. The tumor-only model assumes the variant could occur at any allele frequency. The best starting point for a high-level overview is the user guide:

https://github.com/Illumina/manta/tree/master/docs/userGuide

And the methods writeup for more details:

https://github.com/Illumina/manta/tree/master/docs/methods/primary

This is a latex doc you'll need to clone and render for the latest version. As described above, the supplement provided with the pre-print or final publication are both very good starting points.
