[modeller_usage] Question about compressing Uniprot90

[Dimitrije Jevremovic <>]

I am trying to compress the Uniprot90 FASTA file database into a
binary file using convert() function as provided in examples for the
MODELLER. However, my compressed file ends up being even larger than
the uncompressed original one. What may be the problem here? Here is
the Python code which I a using with MODELLER v9.7.

from modeller import *

log.verbose()
env = environ()

sdb = sequence_db(env)
sdb.convert(seq_database_file='/gne/research/data/bioinfo/modeller/db/uniprot90',
seq_database_format='FASTA',
            chains_list='ALL', minmax_db_seq_len=[30, 4000],
            clean_sequences=True,
outfile='/gne/research/data/bioinfo/modeller/db/uniprot90_pruned.bin')


Kind regards and thank you,
Dimitrije Jevremovic
