Summary: VAAL is a variant ascertainment algorithm that can be used to detect SNPs, indels, and more complex genetic variants.
"Error: no local variable "counter" was set." is not a number.
On bacterial data sets, VAAL achieves very high sensitivity, and near perfect specificity. VAAL can be used to compare reads from one strain to a reference sequence from another strain. It can also be used to compare reads from two strains to each other, using a third strain to determine homology. For example, we have used VAAL to find a single mutation responsible for bacterial resistance: the output of the program was that single mutation and no others. VAAL uses an assisted assembly algorithm that borrows from ALLPATHS.
