Incomplete sample_type in model configs leads to dorado error

[elihuihms]

I've encountered an issue when exporting bonito models with the sample_type = "rna" in their config.toml files. When models with this sample type are exported via bonito export, dorado fails to load the model with a Failed to resolve basecaller models: Failed to determine model sample type from model name or config error.

e.g. rna004_130bps_sup@v5.2.0:

[run_info]
sample_type = "rna"
sample_rate = 4000

This seems to be an issue with just the 5.x.x series of super accuracy models, and the fix is simple:

[run_info]
sample_type = "rna004"
sample_rate = 4000

Thanks for raising this one, we're aware of it and in the v5.3.0-RNA models released in v1.1.0 we've set the sample type to rna004.

Unfortunately we don't have plans to revise the previously released models as this often leads to more confusion with models not matching between different bonito versions and/or unexpected default behaviour.

I'll leave this issue open for now for visibility and to demonstrate the simple workaround.
