Just to add that these are IMS files and that we have "patched" FIJI with the latest netCDF file with the jar from here:

Hi,

We have a customer in Australia that is acquiring large Multi-point datasets. Can be upwards of 500GB data sets each time.

They capture full Frame, no Binning (1024x1024 pixels), dual channel ( 2 simultaneous cameras acquiring) and 60-100 Z planes on multiple X/Y positions in an overnight (timelapse) protocol. These files can be upwards of 80Gb per XY position.

The problem they have is when they try and import these large data sets to FIJI it fails, however if they perform a similar experiment, only smaller in size there is no issue.

After asking the customer to perform a couple of tests for us, this is what they discovered:

"Definitely looks to be a file size issue.  Tried the smaller 1.5Gb files yesterday and it worked fine.  Did a longer experiment (same experimental setup just with more z-slices and more time points so the file was around 60Gb and these are failing.   The only other difference was that the small files that worked had been captured using two channel sequential while the large files that don't work were captured with dual channel simultaneous capture."

Any advice/workaround you can supply for handling these larger datasets would be appreciated.

Best,
