[NeuroAnalyzer.jl](https://juliahub.com/ui/Packages/General/NeuroAnalyzer): Neurophysiological data analysis with Julia
v0.24.8 is out: [https://codeberg.org/AdamWysokinski/NeuroAnalyzer.jl](https://codeberg.org/AdamWysokinski/NeuroAnalyzer.jl)
- **breaking change** : channels are addressed by their labels, not numbers (breaking change); to convert numbers to labels, use `get_channel(obj, type="eeg")` or `get_channel(obj, ch=["Fp1", "Fp2"])`
- **breaking change** : channels are stored as they are in the recording (physical order); list of channels sorted by their type is stored in `OBJ.header.recording[:channel_order]` (logical order)
- **breaking change** : channels label is stored in `OBJ.header.recording[:label]`, channel unit is stored in `OBJ.header.recording[:unit]`
- list of bad channels is stored in the `OBJ.header.recording[:bad_channel]`
- utils: `get_channel()`
- channels may be addressed by name, e.g. `ch="Fp1"` or `ch=["C3", "C4"]` or by type, e.g. `ch="all"`, `ch="eeg"` or `ch=["mag", "grad"]`
- supports exclude options (default value is “bad”, so bad channels are excluded from the list)
- initial support for MEG data
- io: `import_fiff()` – both MEG and EEG data
- gui: `iview()` – lots of changes:
- select time segment
- delete time segment / epoch
- left click channel label to display its properties
- right click channel label to mark it as bad
- zoom in and out
- scroll with mouse wheel
- toggle scale bars, monochromatic mode, snapping
- plot: `plot_signal()` – lots of changes:
- finally displays properly data with \> 100 channels
- gets list of bad channels from the header
- channels of different type are not displayed separately, but in logical order
- scale bars and units are drawn for each channel type
- process: `denoise_cwt()` – denoise using continuous wavelet transformation
- process: `remove_cwt()` – remove artifacts using continuous wavelet transformation
- analyze: `cwtspectrogram()` – improved CWT scaleogram
- analyze: `psd()` – new methods: `:gh`, `:cwt`
- code cleanup
- many minor additions and fixes
