nf-core demo (local)

[KerryAM-R]

I've been trying to worth through the nf-core tutorial of running into an issue with the

nextflow run nf-core/demo -profile conda,test --outdir demo-results-notrim --skip_trim -resume

However I get the error

ERROR ~ Validation of pipeline parameters failed!

-- Check '.nextflow.log' file for details
The following invalid input values have been detected:

• --skip_trim (true): Value is [string] but should be [boolean]

I then made a json file nano params.json with

{ "skip_trim": true, "outdir": "demo-results-notrim" }

I also needed to use conda

nextflow run nf-core/demo -profile conda,test --outdir demo-results-notrim --skip_trim -resume

So I'm not 100% sure why it kept saying it was. a string even though I wrote it as --skip_trim true or =true or 'true' didn't work, but the JSON did
