Snakefile - problem with too many outputs

Question

[ja4123]

Hey! Part of my snakefile is below:

SAMPLES=["I_1_R1", "I_1_R2"] 
RES = list(set([i.rsplit('_R')[0] for i in SAMPLES]))

rule all:
  input:
    expand("path/{res}_0_5000_R.png", "path/{res}_0_5000_S.png", "path/{res}_500_10000_R.png", "path/{res}_500_10000_S.png", res=RES),
    expand("path/{res}_RvsR.png", "path/{res}_strand_1vs2.png", res=RES),
    expand("path/{res}_log10_500_1000.png", res=RES)

rule statistics:
  input:
    "path/{res}.tsv"
  output:
    dist = "path/{res}_0_5000_R.png", "path/{res}_0_5000_S.png", "path/{res}_500_10000_R.png", "path/{res}_500_10000_S.png"
    feature = "path/{res}_RvsR.png", "path/{res}_strand_1vs2.png"
    log10 = "path/{res}_log10_500_1000.png"
  shell:
    "path/statistics.py {input} {output.dist} {output.feature} {output.log10}"

and I have an error like this:

SyntaxError in line 15 of path/Snakefile:
positional argument follows keyword argument

line 15 is:

feature = "path/{res}_RvsR.png", "path/{res}_strand_1vs2.png"

Can someone help or give some advices?

This might seem silly, but you're missing commas between the outputs. Try:

output:
    dist = ["path/{res}_0_5000_R.png", "path/{res}_0_5000_S.png", "path/{res}_500_10000_R.png", "path/{res}_500_10000_S.png"],
    feature = ["path/{res}_RvsR.png", "path/{res}_strand_1vs2.png"],
    log10 = "path/{res}_log10_500_1000.png"

Try:

feature = ["path/{res}_RvsR.png", "path/{res}_strand_1vs2.png"],

Or:

feature1 = "path/{res}_RvsR.png",
feature2 =  "path/{res}_strand_1vs2.png"

first try does not work, error is:

invalid syntax

second try will not work because of order of execution statistics.py
