Processing raw data from a Teledyne RDI Workhorse Sentinel 600 kHz

[SMTETH005]

I am working with archival data from a Teledyne RDI Workhorse Sentinel 600 kHz. I think the raw .000 files are in some non-standard format. When I try to process using the create_nc.py template I get this error:

Traceback (most recent call last):
  File "pycurrents_ADCP_processing/create_nc_GB1.py", line 24, in <module>
    ncnames_L0 = ADCP_processing_L0_L1.nc_create_L0_L1(in_file=f, file_meta=meta, dest_dir=dest_dir, level=0)

    raise RuntimeError('first 6 bytes of header parse as %s'%str(tup))
RuntimeError: first 6 bytes of header parse as (127, 121, 86, 1)

I was wondering if anyone could give me a hand in figuring this out? I have attached some metadata below and added a link to the raw data itself. Any help would be very much appreciated. Thanks!

Here is the link to the actual raw data file:

Hi Ethan,

I would suggest reaching out to the folks at the University of Hawaii who wrote the pycurrents package about this issue (if you haven't already), since pycurrents_ADCP_processing relies on pycurrents to read in the raw ADCP data. Their email is at the top of this page: https://currents.soest.hawaii.edu/docs/adcp_doc/codas_setup/updating/index.html.

If you're on a short timeline and are familiar with R, I was able to read in your file using the R oce package with a few warnings thrown. You can read more about it at https://dankelley.github.io/oce/reference/read.adp.rdi.html#ref-examples.

My apologies for the delay in getting back to you, and that I can't be of more help!

Thank you for the response, I appreciate it!
