Question: What does input of "path '*'" do in script6.nf? about training HOT 1 CLOSED

The input block has the following format:

input:
<input qualifier> <input name>

The input qualifier specifies what type of input this process expects. The path qualifier says it's either a single file, multiple files, single folder or multiple folders. For teh path qualifier, the input name can either be a variable or the name of the file/folder. If the MULTIQC expected a single file named my_input.csv, we'd have:

input:
path 'my_input.csv'

But if you follow the workflow scope of the script6.nf, you'll see we use the collect channel operator before providing the input to the MULTIQC process, which means that every channel element is a list with multiple files/folders, so even a single MULTIQC task will receive multiple files as instances. These files will be staged in the task folder. So when we say path '*' in the MULTIQC process, we're just saying to use all these files as input to this process.
