Local Dorado models are not being recognised

[ekg123]

Hello,

We have a somewhat restrictive IT security environment around our HPC and I can download and save the models using a machine from outside the network that hosts the HPC we have access to, and I can put the saved models in whatever directory is needed by uploading the models I saved previously elsewhere. Despite supplying the models in /bin /dorado or /dorado-models, I keep getting the following error when calling Dorado like so:

./dorado basecaller --emit-fastq dna_r10.4.1_e8.2_400bps_fast@v4.1.0 /scratch/<user_specific_path>/PBL_test_pod5 > dorado_log_20240516.log

I understand the desire of ONT to have tight control over models to ensure ONT products are performing as intended, but is there a way to get around this and force Dorado to find the models in a specific location? Attempting to download the models never works (and wont) as getting a cert to do so on our HPC is not easy/common/permitted.

Best wishes
Eddie

Hi,
You can use models in any location by passing the path of the model folder to dorado instead of the model name.
