To CARTA users, this repo holds the CARTA release packages. Please use this repo to log bugs and feature requests. These will be triaged by the development team and prioritised as necessary in the development cycles.
Describe the bug
CASA's imageconcat produces .image (and other) files that contain other .image files within, and these load extremely slowly.
If I try to change frames while the spectrum is loading, I have to wait until it's done before the image changes - and this can be 5-10 minutes on typical cubes (56 GB)
To Reproduce
Steps to reproduce the behavior:
Create an image cube comprised of many sub-cubes using imageconcat with mode='m' or mode='c'
Try to view a spectrum
Wait.
Expected behavior
Performance comparable to that of "normal" cubes, and/or, an option to stop loading the spectrum partway through.
Platform info (please complete the following information):
OS: RH
Browser: Chrome
Version 4.0b1
Additional context
I expect this is somewhat, but probably not entirely, hardware- and filesystem-dependent.
I'm going to work around the issue by re-making my concat'd cubes with mode='p', but it would be best if we could use both types.
