wrsamp: IndexError: Channel 0 contains values outside the allowed range [-32768, 32767] for fmt 16

We're encountering an issue when trying to write data to WFDB files using the wrsamp function. Specifically, we’re seeing an error that prevents us from writing the files correctly. When attempting to call wrsamp to save our data, we receive the following error message:

IndexError: Channel 0 contains values outside the allowed range [-32768, 32767] for fmt 16.

To investigate the issue further, we modified the WFDB source code to provide additional debugging information. The csv file we’re attempting to convert to wfdb has values ranging between:

Minimum: -90.113269
Maximum: 622.269327

But this is being scaled to -32767 and 32772 after calling wrsamp, so the max value allowed in fmt 16 is being exceeded.

We are using package versions:

Please see a screenshot below depicting the error we get using:
wfdb==4.1.2
pandas==2.2.3
numpy==2.1.2

We have a minimal reproducible sample that we sent to Ben Moody and Tom Pollard.

Inizia riproducendo la chiamata a wrsamp con l’intervallo di input indicato e verifica come vengono ridimensionati i valori per fmt 16 prima del controllo dell’intervallo. Il payload non indica file sorgente né test; il lavoro è completato quando i dati descritti possono essere scritti senza produrre valori al di fuori dell’intervallo fmt 16 consentito, con copertura di regressione per il caso.
