Create extended counts file only if it contains information?

[mschubert]

I'm running guide-counter for a custom use case that does not have the typical control, essential and non-essential genes of a CRISPR viability screen. So I do not use any of the options:

• --control-guides
• --control-pattern
• --essential-genes
• --nonessential-genes

As such, the output.extended-counts.txt does not contain any additional information compared to the output.counts.txt. Does it make sense to skip generation of output.extended-counts.txt if none of the above parameters are specified?
