Bambus2
From AMOS WIKI
Getting data into Bambus 2 can be a pain. Here is my recipe:
toAmos \ -s my.fa \ -c my.contig \ -m my.mates \ -o my.afg
You need the .fa to list the contigs within the GFD-like contig file (annoying but true). You don't need accurate sequences in the .fa, you just need something to make the format valid. The .contig and .mates are as expected for Bambus.
The resulting .afg is then 'banked' with:
bank-transact -c \ -b my.bnk \ -m my.afg
