What's New:

When selecting the EEG signal with the left mouse button, a green rectangle is drawn. Now, the height of this rectangle (in microvolts), as well as the peak-to-peak amplitude of the EEG signal within the rectangle (in microvolts) are displayed.
A help menu has been added. Currently, it includes a diagram explaining the amplitude and time values associated with the green rectangle.
In the configuration window, channels are now numbered, making it easier to select the correct channel for the spectrogram.

Bug Fixes

Fixed an error where the amplitude values displayed on top of the green rectangle, drawn when selecting the EEG signal with the left mouse button, were incorrect.

What's New:

The option to load sleep stages from .txt files: Sleep scoring saved as .txt files can now be loaded. Each line of the .txt file should have the sleep stage of one epoch, meaning that the sleep stage of all epochs are separated by a new line. Wake can be represented as W, Wake, or WAKE; REM as R, Rem, or REM; and N1, N2, and N3 as N1, N2, N3 or NREM1, NREM2, NREM3, respectively.
The option to load EEG data from .EDF files: EEG data stored as .EDF files can now be loaded. The program assumes the data is in microvolts and no scaling is applied, due to the variability in how individual EDF read/write routines handle specific header fields. If the data does not display correctly, it is likely because the actual amplitude values are not in microvolts. The unit field of the data is ignored within ScoringHero.
The option to change time units on the EEG X-axis: The time unit of the EEG x-axis can now be changed to seconds, minutes, or hours. This is particularly useful for data recorded over several hours, where displaying time in seconds may not provide useful information.
Additional event labels: Three more event labels have been added, connected to the function keys "F10", "F11", and "F12".
Spectrogram time axis ticks adjustment: The time axis ticks on the spectrogram now adjust to the length of the recording. Previously, they were fixed to show every hour, which resulted in no time labels for data shorter than one hour.

Bug Fixes

Fixed an error where loading sleep scoring data saved as .vis files did not create an output file which adheres to the current structure of sleep scoring files ScoringHero uses (.json).

What's new:

There were reports that users habituated to the warning message pop-up window which, upon closing the software, informed the user in case there were unscored epochs. The warning window now only pops up when < 50% of epochs are not scored, assuming that the user is either very well aware of the remaining unscored epochs or did not intend to sleep score the night in the first place when more than 50% of epochs are left unscored.
The warning pop-up window now shows the number of unscored epochs and instructs how to find the remaining unscored epochs.

Bug fixes:

Fixed an error where resetting the sleep stage of an epoch back to None unintentionally set it to "None" (as a string rather than the None value). This could result in both None values and "None" strings to occur in the final scoring file (filename.json).
Fixed an error where loading a new dataset could crash the software when the current epoch displayed was out of range in respect to the number of epochs of the new dataset.
Fixed an error where changing the epoch duration (in s) or sampling rate (in Hz) from the configuration pop-up window would cause the epoch line indicator within the hypnogram to malfunction.
Fixed an error where changing the epoch duration (in s) or sampling rate (in Hz) from the configuration pop-up window would not adjust the number of epochs for the final scoring file (filename.json).
