Release Notes

Version 9.2 of 19-Mar-2008

• 18-Mar-2008 19:07:39
  Improvement: Embla data format - Select a recording folder instead of a recording file to create sessions. This ensures a better data format support and an increased flexibility for those recording several animals simultaneously and undertaking analysis separately (pra_open, pra_load, open_embla, read_embla).
  
• 18-Mar-2008 19:07:39
  Improvement: Conventional display of human ASDA and animal sleep/wake stages (hpn_plot, pra_command, viewer, etc.).
  
• 27-Feb-2008 14:08:28
  New Feature: Additional algorithms for BSS denoising (pra_ica, /external).
  
• 26-Feb-2008 18:50:33
  New Feature: Band-stop 50/60 Hz Notch filter added (pra_filter).
  Reminder: Band-pass, high-pass and low-pass filters available using selectable cutoff frequency.
  New Feature: Elliptic filter type added (pra_filter).
  Elliptic filters offer steeper rolloff characteristics than Butterworth or Chebyshev filters, but are equiripple in both the pass- and stopbands. In general, elliptic filters meet given performance specifications with the lowest order of any filter type.
  New Feature: Chebyshev Type I filter type added (pra_filter).
  Chebyshev Type I filters are equiripple in the passband and monotonic in the stopband. Type I filters roll off faster than type II filters, but at the expense of greater deviation from unity in the passband.
  New Feature: Chebyshev Type II filter type added (pra_filter).
  Chebyshev Type II filters are monotonic in the passband and equiripple in the stopband. Type II filters do not roll off as fast as type I filters, but are free of passband ripple.
  Reminder: Butterworth filter type available (pra_filter).
  Butterworth filters are characterized by a magnitude response that is maximally flat in the passband and monotonic overall. Butterworth filters sacrifice rolloff steepness for monotonicity in the pass- and stopbands. Unless the smoothness of the Butterworth filter is needed, an elliptic or Chebyshev filter can generally provide steeper rolloff characteristics with a lower filter order.
  Reminder: FFT/iFFT filter type available (pra_filter).
  Combined used of FFT anf FFT inverse allows implementig Finite Impulse Response filters in the frequency domain. FFT/iFFT filters suffers from the limitations of the FFT method. Spectral leakage may results in waveform distortion.
  
• 22-Feb-2008 18:11:47
  New Feature: Display of filtering settings in the Viewer traces panel (pra_display).
  
• 22-Feb-2008 15:39:03
  New Feature: Interval variability analysis is now scriptable. It can be called from the command line with an input filename of from the Manager where it is associated with Inter-beat Intervals and Events files (manager, iva_analysis).
  
• 20-Feb-2008 17:16:04
  Improvement: GUI screen export into JPEG image now always using portrait orientation (pra_export).
  
• 16-Feb-2008 17:16:41
  New Feature: When folder structure has changed, Viewer automatically searches all subfolders of the default recording folder to match the requested session recording (pra_open, pra_load, pra_subdir).
  
• 14-Feb-2008 19:27:20
  New Feature: New data format support for generic ASCII Raw Time Series (open_txt, read_txt).
  
• 08-Feb-2008 21:26:42
  New Feature: Platform-independent archival and compression of all session-related results using 7zip (manager).
  
• 23-Jan-2008 21:52:37

• 22-Jan-2008 18:36:54
  New Feature: Automatic generation of release notes (ASCII and HTML format; makefile.m).

• 18-Jan-2008 12:35:48
  New feature: MD5 generation and verification function supporting all UNIX, GNU Linux and Windows OS (md5.m, md5.exe, md5.html).
  
• 17-Jan-2008 18:14:23
  New feature: When marking mode is activated, pressing the keyboard's space bar nows marks current page as a generalized artifact (event.m, pra_keyfcn.m).
  
• 16-Jan-2008 13:13:42
  New feature: While scoring mode activated and first epoch selected, the new "cut" command (keyboard shortcut: "ctrl + c") deletes the first epoch and shifts scoring start one epoch forward (hpn_score.m, pra_keyfcn.m).
  Reminder: While scoring mode activated, the "delete" command (keyboard shortcut: "ctrl + d") deletes the current epoch which thus shortens scoring time range from one epoch.
  Reminder: While scoring mode activated, the "insert" command (keyboard shortcut: "ctrl + i") inserts an undetermined epoch at the current epoch which thus lengthtens scoring time range from one epoch.
  
• 16-Jan-2008 08:09:21
  Improvement: Hurst exponent feature extraction function now optimized and better reflects transitional stages (pra_hurst_exponent.m from Guillaume Becq).

• 26-Nov-2007 14:18:27
