Read ACE format assembly files
These are typically output by sequence assembly tools, like CAP3 or Phrap.
Documented in the section labelled "ACE FILE FORMAT" at http://bozeman.mbt.washington.edu/consed/distributions/README.14.0.txt
Briefly: each field is a line starting with a two letter code, in some cases followed by data lines termintated by a blank line. Here's an brief example how an ACE file looks like:
AS contigs reads CO contig_name bases reads segments compl (CAP3: segments=0) sequence BQ base_qualities AF read1 compl padded_start_consensus (negatives meaning?) AF read2 .. BS segments RD read1 bases info_items info_tags (latter two set to 0 by CAP3) sequence QA read1 qual_start qual_end align_start align_end DS (phred header? left empty by CAP3) RD read2 ...
As far as I know, this is only used for nucleotide sequences.
