This section of the forum is now closed; we are working on a new support model for WDL that we will share here shortly. For Cromwell-specific issues, see the Cromwell docs and post questions on Github.
alternative command execution based on input parameters?
Do you have an example of a WDL workflow that accepts alternative input parameters, and based on the inputs will execute the workflow accordingly? For example, having a WDL that accepts either bam or fastq files as input. If the bam file is selected, then it will process a different set of initial tasks than if the fastq file was provided.
