I am trying to use larsoft event display to read some 35t raw data that have both a module label and an instance name. The event display does not work if the product has an instance name (i.e. one cannot specify the label as "label:instance" in the configuration box.).

Preliminary analysis show the problem is relatively easy to solve.
Need to check details.

After some mistakes and wrong checks, it turns out the event display can read data products with an instance name.
In the dialogue window Edit > Configure Drawing > RawDrawingOptions, the product label needs to be specified as "ProductLabel:InstanceName" (note the double quotes). Isn't that great?

No, it's not, because the double quotes are stripped by the event display machinery and the next time the window is accessed one has to retype them again.
This is very much beyond LArSoft.

I have published a branch feature/Issue10538 in lareventdisplay that does not solve anything but is still better code.

Follow up in nutools issue #10659 .

While there is no actual solution to the underline problem, probably lying in nutools, a workaround has been provided that the users seem to be happy with.

Waiting for confirmation of the latter statement from the submitters (added in the watch list) before marking as resolved.

I confirm using quotation mark and colon I am able to plot raw digits in the event display. Thank you so much for your investigation and recipe.

Marking as resolved.
It would be good if the glitch from nutools could be resolved, too.
