+removeChar.pl is a Perl script allowing to remove positions (or columns) of an aligned multi-Fasta file in function of a given character (eg. N).
+The resulting multi-Fasta file corresponds to the same input multiFasta alignment file without the queried character.
+
+This script belongs to the getSequenceInfo supplementary tools.
