Hi @PhD-GOAT,

Thanks for reporting on this issue. I have just submitted a fix here, but I might wait for a few weeks before releasing a new version of YASA on PyPI. In the meantime, the following code should work:

import pandas as pd
import yasa

hypno = pd.read_csv("yasa_example_night_young_hypno.csv")
# Convert to the new Hypnogram format, assuming that the hypnogram is at 30-seconds resolution
hyp = yasa.Hypnogram(yasa.hypno_int_to_str(hypno), freq="30s")
yasa.plot_hypnogram(hyp)

Let me know if that worked for you,

Thanks,
Raphael
