(WARNING: setting it too high (>50)
-
might result in significant overcalling!)

-
minimum overlap between read and haplotype
- --maxReadLength arg (=500)

- --maxHapReadProd arg (=10000000)
-
skip if product of number of reads and haplotypes exceeds this value
- --changeINStoN
-
change sequence of inserted sequence to 'N', so that no penalty is incurred if a read mismatches the inserted sequence
parameters for --pooled option:
- --bayesa0 arg (=0.001)
-
Dirichlet a0 parameter haplotype frequency prior
- --bayesType arg (=singlevariant) Bayesian EM program type (all or
-
singlevariant or priorpersite)
General algorithm filtering options:
--checkAllCIGARs arg (=1) include all indels at the position of the call site
