I'd like to stay in the loop on this as I've been dealing with masking myself but not in the most sustainable way. My use case was creating a mask...

A tangentially related note on masks which I thought I would leave here, I've added some mask creation utilities to diffsims [here](https://github.com/pyxem/diffsims/pull/154). In addition, I've found a rough but O.K....

Looks interesting, I had honestly never heard of `zarr` before. I've followed discussions with @uellue who was very much in the anti-HDF5 camp from the viewpoint of performance and pointed...

@CSSFrancis had a glancing look at where you did [here](https://github.com/CSSFrancis/SeqIO/blob/344ce06fed1f898c6a6b4e561bb55ff36cb2842a/SeqIO/SeqReader.py#L138) and thought maybe you might be able to get some ideas from what I made [here](https://github.com/din14970/hyperspy/blob/a1bee7caf10dcac17a9785eb38a715bf594e3dc2/hyperspy/io_plugins/tvips.py#L209) and [here](https://github.com/din14970/hyperspy/blob/03801197fb175e6d7c9d002965aa3cb7710df8cd/hyperspy/io_plugins/blockfile.py#L409). Maybe I'm...

@CSSFrancis the memmap strategy will work if there is a predictable header/block size between frames. Whatever is the repeating element in the file you just create a custom `dtype` for...

to be honest I've never actually experienced significant slowdowns due to rechunking, only by trying to do operations on inappropriately chunked data. I tend to always rechunk depending on the...
