Warning during normalize-by-median #131

Open danbacastro opened 10 years ago

danbacastro commented 10 years ago

Hello everybody,

I'm getting the following message during the normalize-by-median of my unpaired sequences:

* WARNING: hashsize is default! You absodefly want to increase this! * Please read the docs!

My commands are listed below:

interleave-reads.py -o "metagen1.trimmed.interleaved.fastq metagen1.trimmed_R1.fastq / metagen1.trimmed_R2.fastq; normalize-by-median.py -p -k 20 -C 20 -N 4 -x 10e9 -s normC20k20.kh .interleaved.fastq; normalize-by-median.py -C 20 -l normC20k20.kh -s normC20k20.kh unpaired.fastq;

The first normalize-by-median runs without any warning, but the second displays that. The output looks right, should I be worried about it?

Thank you in advance,

Daniel

Hi Daniel,

thanks for the e-mail! This should be fixed in versions more recent than March - what version of khmer are you using?

thanks, --titus

Hi Dr Titus,

I'm using khmer 0.6.1. The output looks right, should I be worried about it?

Thanks

No, khmer 0.6.1 works mostly OK, but you should upgrade to khmer 1.1 when you can! We've made a LOT of changes, all in the (hopefully) positive direction.

best,

Let us know how it goes -- should be mostly painless!
