cuffdiff error "number of labels must match number of conditions"

Question

[Bioiris]

Hello, I use cuffdiff qualification of 20 .bam files

in my snakemake, I have

cuffdiff rule:

     input: bam = expand ( "output / bam / smp {} .bam" smp = config ["samples"] split ().)

     output: "output / cuffdiff / done"

     params: gtf = config [ "gtf"], args = config [ "cuffdiff"] [ "args"] = labels config ["samples"] split ().

     Threads: config [ "cuffdiff"] [ "threads"]

     message: "" "--- cuffdiff contifiquation." ""

     shell: """

 cuffdiff -p {threads} -o {output} -L  {input.bam} {params.gtf} {input.bam}

 touch {output} """

but, i have this error

"" "You are using Cufflinks v2.2.1, qui est The Most recent release.

Error: number of labels must match number of conditions' ""

can anyone help me ??

thank you in advance

See this error in cuffdiff ---(mutiple sample comparision) for how to specify labels for the conditions being compared. If you have only one condition (control, test) then there will be two labels.

Please post the actual command used.

Previously I also faced this problem and a solution given in this thread by Devon Ryan solved it.
