generate an unkown file in input

Hello,

It's me again for a new snakemake question!
This time, I want to read a table in input using a R script, to generate a list of reads to keep. But this list may came from multiple source, (genotype in this case).

I generate with my R script an output file {barecode}_list_{genotype}.txt .
barecode wildcard is already defined, and genotype can be either A/B/C/...

I tried something like this:

rule R_HBV_analysis:
input:
    R_data = datapath+"BLASTN/{barcode}_fmt.txt"
output:
    Rresult = datapath+"R_RESULT/{barcode}_list_{genotype}.txt",
wildcard_constraints:
    genotype =["GTA","GTB","GTC","GTD","GTE","GTF","GTG","GTH","GTI","GTJ"]

params:
    path = datapath  
shell:
    """
    if [ ! -d {params.path}RDATA ];then
        mkdir {params.path}RDATA
    fi
    if [ ! -d {params.path}R_RESULT ];then
        mkdir {params.path}R_RESULT
    fi
    Rscript script/HBV_analysis.R {input} {params.path}
    """

with

(GENOTYPE)={}
GENOTYPE['genotype'] =("GTA","GTB","GTC","GTD","GTE","GTF","GTG","GTH","GTI","GTJ")
rule all:
input:
    Rresults = expand(datapath+"R_RESULT/{barcode}_list_{genotype}.txt",barcode=BARCODE,genotype=GENOTYPE['genotype'])

But it return me an error, because snakemake expect a file for all genotypes, wich is not the case.

I hope I was clear in my question.
thanks,

Hadrien
