Editing CSV Files on IDAS

Starting on December 31, 2022, users will be able to create, open, and make basic edits to CSV files on IDAS. This is a new feature that will be added to IDAS during our maintenance on December 28-30, 2022.

1. Log in to IDAS from https://notebooks.hpc.uiowa.edu/

2. RStudio users may need to take an additional step to navigate to JupyterLab:

    a. If you use the "Research Interactive" instance on IDAS, access JupyterLab (please fill in your HawkID): https://notebooks.hpc.uiowa.edu/research-interactive/user/HAWKID/lab

    b. If you use one of the course instances on IDAS and your instructor chose RStudio as the default interface, you can change the end of the URL from "rstudio" to "lab", so that the URL follows the following format: https://notebooks.hpc.uiowa.edu/CLASS-NAME/user/HAWKID/lab/
