Hello, I'm having issues with uploading RHS files from Intan. The read_Intan_RHS2000_bst_2018.m file is having issues what appears difference in array sizes (see attachment). I don't have any issues with reading in the files when using Intan's read_Intan_RHS2000_file.m script, which I'm guessing is the foundation for Brainstorm's script to read it in. Could someone help me with triaging this issue?
Using MATLAB 2022b on a Windows 64-bit computer
Indeed, read_Intan_RHS2000_bst_2018.m is based on read_Intan_RHS2000_file.m.
Can you please share a short example file, for us to try and reproduce this issue?
(upload the file somewhere and post the download link here)
Also check this thread on reading .rhd files with read_Intan_RHD2000_bst_2022 based on read_Intan_RHD2000_file, it may point to insights on what is going with your file

@Raymundo.Cassani the only files I have to share are ~770 MB. Is that too big?
Thanks for the additional forum post. It didn't set off any alarm bells but I'm in the process of analyzing the code to see if I can make heads of tails of things.
These are the variables that I get when I run {read_Intan_RHS2000_file.m}

amp_settle_data 108x1800064 194406912 logical

The issue appears when extracting digital input channels to separate variables. The board_dig_in_data is a 2x128 matrix due to 2 num_board_dig_in_channels; and board_dig_in_raw is a 1x256. I'm not exactly sure how to correct this though.

Thank you @neuronick for the sample file, it was useful for finding and fixing the bug (commit 696240d)
Update your Brainstorm, instance to get this fix
Thanks for looking into this and providing a fix.
As a note, I created the protocol --> add subject --> import raw data file and didn't work the first time, but I ran the process again and it worked. Not sure why, but I've done this with other MATLAB GUIs before and it's worked. Adding this note in case someone else runs into the same issue.
