Finally a post about geomicrobiology.
Over on github I set up a repo. Most the codes are not comment and there are no docs as of yet.
One that might interest geomicro folks is some code I wrote that parses a genbank file for accession number, location, source of sample, and sequence. I combine this into a fasta for that can then be turned into a tree for doing some biogeography or geomicrobiology. You will need to align your fasta and build the tree.
Code is HERE
