Spyking-circus

=============

* automatic suppression, during meta merging, of noisy templates (for SpikeToolKit/Forest)
* during the phy export, we can automatically pre-assign labels to neurons
* fix a bug when converting to phy with dead channels
* fix a bug when converting to phy with file formats without data_offset
* speedup the estimation of the amplitude distribution
* minor fixes for clusters
* smoothing of the templates thanks to Savitzky-Golay filtering
* fix a bug when launching GUIs for file format without data offset
* can now work with scipy 1.3 and statsmodels 0.10
* isolation mode is improved, set as default and leading to better performance
* reducing overclustering with the Hartigan dip-test of unimodality
* can now set the number of dimensions for local PCA (10 by default)

=============

=============

* add a docker file to build the software
* add support for shanks in phy 2.0
* add support for deconverting in the qt launcher
* do not create a Qt App if merging in auto mode
* waveforms are convolved with a Hanning window to boost PCA
* oversampling in now adapted as function of the sampling rate
* reduction of I/O while oversampling
* speed improvement with undersampling while cleaning the dictionary
* automation of the software for SpikeForest/SpikeToolkit benchmarks
* merging is now included in the default pipeline
* normalization of the metrics in the meta merging GUI

=============

=============

* major improvement in the clustering. No more max_clusters parameters
* much faster clustering (thanks to Ruben Herzog)
* added the statsmodels library as a required dependency
* enhancement of the smart search mode
* enhancement of the bicubic spline interpolation
* fix a typo when using dead times and the collect mode
* fix a minor bug when small amount of spikes are found during smart search
* fix a bug in the wrapper for BRW files
* support for phy 2.0 and phylib
* remove the strongly time shifted templates
* addition of a wrapper for MDA file format
* amplitudes for unfitted spikes is now 1 when exporting to phy
* default install is now qt5, to work with phy 2.0

=============

=============

* cosmetic changes in the GUI
* adding a deconverting method to switch back from phy to MATLAB
* support for the lags between templates in the MATLAB GUI
* warn user if data are corrupted because of interrupted filtering
* robust automatic selection of the centroids (thanks to Ruben Herzog)
* addition of the statsmodels dependency
* remove the max_cluster parameter
* reduction of the size for saved clusters
* display the file name in the header
* fix a nasty bug allowing spikes at the border of chunks to be fitted even during dead periods

=============

=============

* fix a bug for MPICH when large dictionaries.
* fix a bug for numpy files when used with new numpy versions
* add the possibility to subtract one channel as a reference channel from others
* native support for blackrock files (only .ns5 tested so far)
* simplifications in the parameter file
* fix for display of progress bars with tqdm
* addition of a multi-folders mode for openephys
* hide GPU support for now, as this is not actively maintained and optimized
* fix in the MATLAB GUI for float32 data
* fix the broken log files
* default cpu number is now half the available cores

=============

=============

* fix a regression with spline interpolation, more investigation needed
