-o outfile not working with --mink ?

[rotheconrad]

I am using this command: idba_ud -r ${infile} --mink 55 --maxk 124 --min_contig 500 --num_threads 10 -o ${oufile} or this: idba_ud -r ${infile} --mink 55 --min_contig 500 --num_threads 10 -o ${oufile} idba_ud -r ${infile} --mink 83 --min_contig 500 --num_threads 10 -o ${oufile} idba_ud -r ${infile} --mink 101 --min_contig 500 --num_threads 10 -o ${oufile}

which creates an unspecified directory for the assembly called 895319?

I don't know where this number comes from. It is not what I tell it.

If I use this command: idba_ud -r ${infile} -o ${outfile} --min_contig 500 --num_threads 10

I get the actual output directory I specify.

Any thoughts? Thank you.
