Problem using "into" operator to duplicate channels

[espelpz]

I need to use the same channel multiple times so I'm trying to create copies of it using the into operator in this way:

Saving path of interest in a channel:

if (params.fasta) { ch_fasta = file(params.fasta, checkIfExists: true) }

Replicating that channel for using its content in different nextflow processes:

ch_fasta .into { ch_fasta_bwamap ch_fasta_bwaindex ch_fasta_picarddict ch_fasta_bwamapcons ch_fasta_filtercons ch_fasta_clipbam ch_fasta_mutect2 ch_fasta_vardict }

However, when I try to do this I obtain this error message from nextflow:

mar-03 15:10:45.170 [main] DEBUG nextflow.Session - Session aborted -- Cause: No signature of method: sun.nio.fs.UnixPath.into() is applicable for argument types: (Script_2a703cbc$_runScript_closure2) values: [Script_2a703cbc$_runScript_closure2@2dc3ece8] Possible solutions: inits(), init(), any(), min(), list(), find() mar-03 15:10:45.193 [main] ERROR nextflow.cli.Launcher - @unknown groovy.lang.MissingMethodException: No signature of method: sun.nio.fs.UnixPath.into() is applicable for argument types: (Script_2a703cbc$_runScript_closure2) values: [Script_2a703cbc$_runScript_closure2@2dc3ece8] Possible solutions: inits(), init(), any(), min(), list(), find()

So, I'm not able to duplicate the channel eventhough in the past I have used this operator in this way to do that... I don't know what I'm doing wrong or how I can do this in another way.

Hope someone can help me, thank you!

You didn't actually create a channel at the start, just a file object. You should instead use Channel.fromPath().
