I run this command in order to filter short length sequences less than 290 nt.  
My problem is it is running more than 24 hours.

qiime rescript filter-seqs-length-by-taxon \

> ```
> --i-sequences RefsequencesdsrB.qza \
> --i-taxonomy dsrB.qza \
> --p-labels bacteria \
> --p-min-lens 290 \
> --o-filtered-seqs ncbi-refseqsnew.qza \
> --o-discarded-seqs ncbi-refseqs-tooshortnew.qza
> 
> ```

Is there option/parameter to know how long should I wait for? Is there a problem? It sounds unusual, I suppose!

Best regards,  
Qiimer

Hi @TurboQiimer,

How many sequences are in your `RefsequencesdsrB.qza` file?

How may different taxonomic groups are in your `dsrB.qza` file?

Are there only `Bacteria` in your data file? If so make use of the

`qiime rescript filter-seqs-length`

action, it is much faster as it will trim all filter all sequences to that `min-lens`. I would not use

`rescript filter-seqs-length-by-taxon`

unless you want to differentially filter multiple taxa.
