mmseqs search return no results

[Leo-T-Zang]

Expected Behavior

Expect search return identity value for query sequences

Current Behavior

No values (identity) has been returned.

Steps to Reproduce (for bugs)

Data can be found here: link

# Create MMseqs2 databases
mmseqs createdb gen.fasta gen_db
mmseqs createdb train.fasta train_db

# Perform the search
mmseqs search gen_db train_db result tmp -a -s 7.5
mmseqs convertalis gen_db train_db result result.m8

Use python code to read back results

mmseqs_result = pd.read_csv('./mmseq/result.m8', sep='\t', names=[
    'query', 'target', 'identity', 'alignment_length', 
    'mismatches', 'gap_openings', 'qstart', 'qend', 
    'tstart', 'tend', 'evalue', 'bit_score'
])

The dataframe is empty. Does this mean there is no identity (0 identity) for my query sequences in target set?

Hi MMseqs Team,

Can anyone help me with this problem?

Thanks a lot!
