Hi @veprbl, I would also like to add to the combined png file, e.g. Can I add DCA also to the below rule by passing two expand (one for DCAT and other for DCAz) in the input? if yes how to redefine the command in this case?
montage -mode concatenate {input[0]} {output} || true
montage -mode concatenate {input[1]} {output} || true
montage -mode concatenate {input[2]} {output} || true

or I define a new rule for each? Similar thing, I will also do for rule "tracking_performance" to produce results in directory("results/tracking_performances/{CAMPAIGN}/").

rule tracking_performance_debug_montage:
input:
expand(
[
"{{CAMPAIGN}}/Debug_Plots/{SEEDING}/pi-/mom/{SEEDING}mom_resol_mom{MOMENTUM:.1f}{{ETA_BIN}}.png",
],
MOMENTUM=[0.5, 1.0, 2.0, 5.0, 10.0, 20.0],
SEEDING=["truth", "real"],
),
output:
"{CAMPAIGN}/Debug_Plots/pi-/mom/mom_resol_debug_{ETA_BIN}.png",
shell:
"""
montage -mode concatenate {input} {output} || true
ls {output}
"""
