Thanks Kato!
Your second version is much better. Is it possible to remove the tabs within the sequence fields? i.e. merge the sequence to a single field instead of being separated with the tab. gsub the first "\n" with "\t", but gsub the second "\n" and after with nothing. One step from what I want.
Merry Christmas!!!

NAME
Bio::AlignIO::largemultifasta - Largemultifasta MSA Sequence input/output stream
SYNOPSIS
Do not use this module directly. Use it via the Bio::AlignIO class.
DESCRIPTION
This object can transform Bio::SimpleAlign objects to and from largemultifasta flat file databases. This is for the fasta sequence format
NOT FastA analysis program. To process the pairwise alignments from a FastA (FastX, FastN, FastP, tFastA, etc) use the Bio::SearchIO
module.
Reimplementation of Bio::AlignIO::fasta modules so that creates temporary files instead of keeping the whole sequences in memory.
FEEDBACK
Support
Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address
it. Please include a thorough description of the problem with code and data examples if at all possible.
