Thank you so much for your 'perfect' answer.
We can advance our discussion based on your thoughts.
I want your opinion regarding the comparison of sleep parameters calculated by LUNA, as I don't have much experience in multi-center research.
Now, we can compare the sleep data from multiple facilities thanks to the effort of the NSRR team. What I want to know is if there are problems in directly comparing the data acquired with different PSG systems and conditions.
Putting aside the inter-rater variability in sleep scoring, should I avoid directly comparing the results of PSG analysis (e.g., frequency analysis or sleep microarchitecture parameters such as SO and spindle) using data from different facilities?
Are there any guidelines or recommended methods that enable us to make a direct comparison?
Thank you so much for your quick and kind reply!
I truly appreciate it.
Thank you as always for your kind support.
I want to analyze the PSG data from NCH Sleep Data Bank using LUNA. I created a sample list from edf and annotation files (.tsv), but LUNA returned the following error message to any analysis.
“error : invalid interval (start) : onset duration description”
I’d appreciate it if you would tell me how to deal with it.
