Error with nf-core rnaseq 2.0

[Abhinav-Mittal]

Hi,
nextflow run nf-core/rnaseq -r 2.0 -profile test,singularity --outdir work is giving error

Include statement is not allowed within a workflow definition

while nextflow run nf-core/rnaseq -r 3.18.0 -profile test,singularity --outdir work is working perfectly fine. What could be the reason?

The version 2.0 of nf-core/rnaseq is about 5 years old. At the time, include statements were allowed within a workflow definition. Currenlty, Nextflow does not support that anymore.

Is there a way to use featureCounts for gene counts instead of salmon or rsem?
