Question: How to insert new data into a recording object. Purpose: "remove_artifacts" by inserting our own cleaned data

Hello,

Contex:
We have a recording that includes Intracortical Microstimulation (ICMS) multiple times during the session. The data is in NWB format originally.
A collaborator has implemented an artifact removal using ERAASR (https://github.com/djoshea/eraasr) and provided a Matlab file with:

1. A matrix of [nSnippet X nChans X nStim] which contains snippets (length = nSnippet) of the high-pass filtered & centered cleaned traces for all the channels (nChans) from all the ICMS epochs (nStim)
2. An array of size [nStim] which contains the start_sample_index of each snippet.

Now, I'm working out how to insert these clean traces into the "filtered & centered" recording object that I got from the same NWB file. Afterward, I will use "neuroconv" to export this recording into a new NWB file (which I have already tested but without the snippet replacement).

Question:
Is there a function to insert these snippets into the recording object?

I hope my question makes sense, if not I can explain anything in further detail.

Thanks for any thoughts and comments on how to approach this.

Best
Pepe

The issue names no files or tests. Start by checking the recording object's API and the neuroconv export workflow for support for replacing snippets at the supplied start_sample_index values. Done means determining whether the cleaned traces can be inserted and exported to a new NWB file.
