User Reference:Parameter Changes for Version 2
This page describes changes in parameters between prior versions of BCI2000, and Version 2.0.
Rows without notes represent parameters that have been renamed without changing their structure or meaning.
Source Modules | ||
| Name in Version 2 | Name in previous versions | Notes |
|---|---|---|
| ID_System, ID_Amp, ID_Montage | Added for equipment documentation purposes. | |
| SourceCh | SoftwareCh | |
| DataDirectory | FileInitials | |
RandomNumberADC | ||
| SineChannelY | SineChannel | |
| RandomSeed | DoTrueRandom | Non-null value now specifies random seed for testing purposes. |
| SignalType | SignalType | Enumeration now omits float24 type to match gUSBamp source module's SignalType parameter, 0: int16, 1: int32, 2: float32. |
| TransmitCh | Removed to avoid redundancy (number of values in TransmitChList). | |
SignalProcessing | ||
| SpatialFilter | SpatialFilterKernal | |
| NumControlSignals | Chosen automatically to match classifier output. | |
AR Filter | ||
| FirstBinCenter | StartMem + MemBandWidth/2 | Specifying center frequencies appears more intuitive. |
| LastBinCenter | StopMem + MemBandWidth/2 | |
| BinWidth | MemBandWidth | |
| WindowLength | MemWindows | Preferably specified in seconds using an "s" or "ms" suffix to its value. |
| EvaluationsPerBin | MemBandWidth/deltaMem | Avoid accidental misconfigurations, allow for reasonable default value. |
Normalizer (renamed from NormalFilter/StatFilter) | ||
| NormalizerOffsets | XMean, YMean | These are now lists of values, allowing for any number of dimensions in the control signal. |
| NormalizerGains | XGain, YGain | |
| OffsetAdaptation, GainAdaptation | XTrendControl, YTrendControl | |
| NumSegments | SignalWinLth | |
| NormalizerPreprocessing | Data preprocessing (trend removal) prior to computing of statistic. | |
| SegmentingConditions | BaselineCfg | Conditions may now be boolean expressions involving State values. |
LinearClassifier (renamed from ClassFilter) | ||
| Classifier | MUD, MLR | The Classifier matrix parameter is now a sparse representation of a multiplication matrix. Each row corresponds to a non-null entry, and contains 4 columns: input channel, input element (e.g., frequency), output channel, weight. |
| ClassMode | Retained only previous ClassMode value of 1. | |
Application Modules | ||
| WindowWidth | WinWidth | |
| WindowHeight | WinHeight | |
| WindowLeft | WinXpos | |
| WindowTop | WinYpos | |
P3AV | ||
| Stimuli | Matrix | |
| Announcements | FocusOn | |
| Results | Result | |
| NumberOfSequences | NumberOfSeq | |
P3 Speller | ||
| TestMode | P3TestMode | |
| TargetDefinition | TargetDefinitionMatrix | |
| IconHighlightMode | IconHighlight | |
| IconHighlightFactor | HighlightFactor | |
| MinRunLength | (TimeLimit)s | Consistently with other time values, this is now given in blocks. Use an optional "s" to indicate a value in seconds. |
Cursor Task (renamed from D3Box Task) | ||
| ResultDuration | RewardDuration | |
| CameraPos | [CameraX CameraY CameraZ]/32767*100 | Combined into a vector (list of 3 values). We also use the same 0..100 coordinate range throughout. |
| CameraAim | [CameraAimX CameraAimY CameraAimZ]/32767*100 | |
| LightSource | [LightSourceX LightSourceY LightSourceZ]/32767*100 | |
| LightSourceColor | LightSourceR<<16 + LightSourceG<<8 + LightSourceB | Combined into an RGB value. |
| CursorStartPos | [StartCursorX StartCursorY StartCursorZ] | Combined into a vector. |
