2 years ago These changes were created to respond to a specific design challenge related to merging two different probes with different information styles and address changes in lack of generalizability of the nirs toolbox code as well as performance improvements.
Changes: nirs.io.loadHitachi:
- modified to only load the raw MES file nirs.io.loadDirectory
- modified to direct MES.csv to loadHitachi instead of Probe.csv (which is not necessarily the MES file) nirs.io.loadBiopacNIR
- added "loading filename" display external Dictionary
- extensively modified behavior to streamline usability, should not affect legacy behaviors
- Allow support for quick deletion from Dictionary using MyData.stimulus('Nback_0')={} *Allow accessor variables from dictionary to support MyData.stimulus('Nback_0').name
- Allow assignment variables from dictionary to support MyData.stimulus('Nback_0').name = "new Name" *Removed old comments nirs.design.StimulusEvent
- Added count property
- Added ability to directly set and reference items in stimulus ex:stimulus(1) will return the first stimuli stimulus(1).amp will return the amplitude of the first stimuli stimulus(2).amp=2 will set the amplitude of the second instance of the stimuli
- Added ability to merge two stimulus events together ex: myNewStimuli= firstRoundStim+secondRoundStim
- Added ability to remove a stimuli by assigning it to empty ex: stimulus(10)=[]; (will drop the 10th stimuli) by using logical indexing this could allow you to drop "invalid" trials or separate a stimulus by some other measure
- Added ability to initialize a stimulus event object by using a table (with onset, dur, and amp columns)
- extra aligned fields are stored in the metadata (note that metadata is not currently preserved via sorting operations
external.nirsviewer.stimutil_gui
- fixed an issue where if stimulus name was a string (instead of char) it would crash
nirs.core.probe.draw
- modified behavior to draw for all unique SD pairs, instead of only for pairs which contained the first wavelength
nirs.util.makeSDcolors
- modified behavior so that optode colors are properly assigned for all data columns external.nirsvieweer.nirs_viewer
- modified behavior so that colors and lines are displayed only for optodes which currently support the selected wavelength type
nirs.modules.BeerLambertLaw
- increased performance 10x by pre-fetching wavelength info and indexing outside of for-loop
Bug fixes: nirs.io.loadHitachi did not properly capture event markers and could not automatically detect the delimeter type (sometimes comma is used sometimes space is used)
Also fixes to improve legacy Hitachi MES file importing (with support for legacy delimiters (tab and comma style)
