Can't load nd2 high content analysis file with MATLAB

[tg875]

I have been using the bioformats package to load nd2 files through MATLAB for image processing. This has worked without any issues until I received some nd2s from a collaborator. These nd2s are taken in high content mode and each well of the imaging plate is a separate nd2 file.

I can initialize a reader using bfGetReader - loci.formats.ChannelSeparator@3e8f9a77
When I try and initialize this reader on the file I get the following error:

Java exception occurred:

Hi,

This error is likely caused by a conflict between the JPEG2000 library which Bio-Formats uses and other installed libraries which also provide JPEG2000 decoding in MATLAB.

What all toolboxes do you currently have installed? You can view a list of the installed toolboxes using the 'ver' command:
