about bowtie's command --fuzzy

[louis7781x]

Does anyone use option --fuzzy before?

I didn't see the option in bowtie's manual,but when I runned bowtie.

it occurs the result:

Encountered a space parsing the quality string for read FQ7FOXL01EXY1V
If this is a FASTQ file with integer (non-ASCII-encoded) qualities, please
re-run Bowtie with the --integer-quals option. If this is a FASTQ file with
alternate basecall information, please re-run Bowtie with the --fuzzy option.

I have tested this option with --best,option(1)--best option(2)--best --fuzzy,
The result of two options were the same.


If anyone know about --fuzzy,please tell me!!! Thanks
