Extract dataset tool

The “Extract dataset” tool requires the Feature lengths dataset (output from featureCounts). The Feature lengths dataset is available in my workflow, but it is not showing up in the input list. Could you please help me identify what might be wrong?

Hi @Tahleel

Is your input dataset in a collection folder? Or is it a single file?

This tool only works on data that is inside a collection. It will filter that collection folder for one of the files inside of it.

I created a quick example of how it works here → https://usegalaxy.org/u/jen-galaxyproject/h/example-extract-dataset-from-collection

Hopefully this helps to figure out what is going wrong, but please let us know! Or we can follow up more, too.

If you want to share back the output of your workflow, we can help to take a closer look at the data you are inputing to this tool. How to share your work is explained in the banner at this forum. For this problem, we would need the history share link to start with, or you can share back both the history with the inputs/outputs so far, and your workflow. Create the links, then post back in a reply, and me or someone else moderating will try to help more.

If you are following a tutorial, you could also post that back for more context.

Thanks! :slight_smile:
