Set this parameter to your e-mail address to get a summary e-mail with details of the run sent to you when the workflow exits. If set in your user config file (~/.nextflow/config) then you don't need to specify this on the command line for every run.

Default thresholds to determine whether a peptide is considered as a binder are the following: syfpeithi > 50, mhcflurry <=500, mhcnuggets-class-1 <= 500, mhcnuggets-class-2 <= 500, netmhc <= 2, netmhcpan <= 2, netmhcii <= 5, netmhciipan <= 5. Note that the default threshold for NetMHC tools is based on the rank metric. The remaining predictors thresholds are based on affinities. Thresholds can be customized in a JSON file: tool-name:value

Specifies the affinity metric instead of the rank metric used for determining whether a peptide is considered as a binder.

type: boolean

Switches the prediction metric of netMHC tools from rank to affinity. Default: netmhc <= 500, netmhcpan <= 500, netmhcii <= 500, netmhciipan <= 500.

Git commit id for Institutional configs.

type: string
default: master

Base directory for Institutional configs.

hidden
type: string
default: https://raw.githubusercontent.com/nf-core/configs/master

If you're running offline, nextflow will not be able to fetch the institutional config files from the internet. If you don't need them, then this is not a problem. If you do need them, you should download the files from the repo and tell nextflow where to find them with the custom_config_base option. For example:

## Download and unzip the config files  
cd /path/to/my/configs  
wget https://github.com/nf-core/configs/archive/master.zip  
unzip master.zip  
  
## Run the pipeline  
cd /path/to/my/data  
nextflow run /path/to/pipeline/ --custom_config_base /path/to/my/configs/configs-master/  

Note that the nf-core/tools helper package has a download command to download all required pipeline files + singularity containers + institutional configs in one go for you, to make this process easier.
