Function: Map PSLs alignments to new targets using alignments ofthe old target to the new target. Given inPsl and mapPsl, wherethe target of inPsl is the query of mapPsl, create a new PSLwith the query of inPsl aligned to all the targets of mapPsl.If inPsl is a protein to nucleotide alignment and mapPsl is anucleotide to nucleotide alignment, the resulting alignment isnucleotide to nucleotide alignment of a hypothetical mRNA thatwould code for the protein. This is useful as it gives basealignments of spliced codons. A chain file may be used insteadmapPsl.
Function: Validates the format of different genomic files.Exits with a zero status for no errors detected and non-zero for errors.Uses filename 'stdin' to read from stdin.Automatically decompresses Files in .gz, .bz2, .zip, .Z format.Accepts multiple input files of the same type.Writes Error messages to stderr
