Trim a Multiple Sequence Alignment (MSA) to remove hypervariable (gappy) regions with Gblocks
This method trims Multiple Sequence Alignments (MSAs) to capture the conserved blocks that may be more reliable regions from which to compare evolutionary rates, such as for tree building. It uses the method Gblocks.
