One malformed signal in mimic3 matched?

Hi,

I've been using wfdb-python to parse numerics from the mimic3 waveforms database at large. I've found just one file that appears to be unreadable by wfdb, from patient p086831. Here's a minimum example (pulling from the online database):

import wfdb
rec_id = "p086831-2130-12-29-18-28n"
# rec_path = "mimic3wdb/1.0/matched/p08/p086831/"
rec_path = "mimic3wdb-matched/1.0/p08/p086831/"
rec = wfdb.rdrecord(rec_id, pn_dir=rec_path)

ValueError                                Traceback (most recent call last)
Cell In[6], line 6
      4 # rec_path = "mimic3wdb/1.0/matched/p08/p086831/"
      5 rec_path = "mimic3wdb-matched/1.0/p08/p086831/"
----> 6 rec = wfdb.rdrecord(rec_id, pn_dir=rec_path)
...
File .../venv/lib/python3.11/site-packages/wfdb/io/_signal.py:2051, in _check_sig_dims(sig, read_len, n_sig, samps_per_frame)
   2049 for ch in range(n_sig):
   2050     if len(sig[ch]) != samps_per_frame[ch] * read_len:
-> 2051         raise ValueError("Samples were not loaded correctly")

ValueError: Samples were not loaded correctly

This also occurs when pulling the respective .hea and .dat files locally and using wfdb from there.

Perhaps this is an issue with the MIMIC file itself, but I wanted to start here, since I'm not sure how to tell. Might this be a MIMIC bug, or is this a wfdb issue?

Thanks in advance--

Empieza reproduciendo el ejemplo con wfdb.rdrecord para p086831-2130-12-29-18-28n, tanto desde la base de datos en línea como desde los archivos .hea y .dat locales. Inspecciona wfdb/io/_signal.py alrededor de _check_sig_dims y compara las dimensiones de muestra declaradas con los datos cargados. Se considera terminado cuando se determine si la discrepancia se origina en wfdb o en el archivo de MIMIC y se registren las pruebas.
