-***What it does***
-
-This tool reconstitues for each aligned read of an alignment file in SAM/BAM format whether
-a mismatch is annotated in the MD tag, and if that is the case counts the identity of the 
-mismatch relative to the reference sequence. The output is a PDF document with the calculated
-frequency for each mismatch that occured relative to the total number of valid reads and a table
-with the corresponding values. Read length can be limited to a specific read length, and 5 prime and 
-3 prime-most nucleotides of a read can be ignored.

-***Warning***
-
-This tool skips all read that have insertions and has been tested only with bowtie and bowtie2
-generated alignment files.
