Support for vbz compression
Hi, I use this excellent package as part of a workflow for analysis on .fast5 data from Oxford Nanopore. More recent data uses vbz compression instead of gzip (see https://github.com/nanoporetech/vbz_compression?tab=readme-ov-file) and as a result I can no longer parse the datasets with h5read, throwing an error about the compression; " Error: Unable to read dataset. Not all required filters available. Missing filters: vbz " Is it possible for me to build rhd5 against my systems vbz libraries in anyway? All the best.
Ignore me, I've got this working just fine now. It may have just been an updates issue, as I had a lot to do, but for anyone else who is struggling, this link helped; https://github.com/nanoporetech/vbz_compression/issues/21 as well as (obviously) installing the vbz package from the ONT repository, and making sure rhdf5filters and Rhdf5lib were installed from BioConductor. Anyway, thanks for making this super useful package.
Glad you got it sorted. rhdf5filters has only supported VBZ in the most recent release version, so you have to be using Bioconductor 3.18 and rhdf5filters 1.14.0
