I wonder if it is possible to use a .txt file as input parameter for instrument which accepts text field parameter. I want to use this option in a workflow: 1) get user’s simple text input, 2) process this text with some instruments, 3) use the processed text as input parameter for the text field of other instrument. Can I do that?
Yes. Please see the functionality described in the tutorial below for the options.
