← What's in NIRWizard

The NIRWizard workshop

The slides I use to introduce NIRWizard: why it exists, a tour of every workspace, and one recording taken from the raw file to a cortex map. Present them, or read them at your own pace.

What it covers

Why NIRWizard

5 min

The problem it answers, and the three ideas the application is built on: data blocks that are never overwritten, a record on every result, and projects that restore their state.

The tour

30 min

Every workspace in a slide or two: quality control, preprocessing, the plots, GLM, block average, connectivity, ROIs, DOT, the Study and exports.

One workflow, end to end

10 min

One participant and one motor task, taken from the raw file to a saved project in seven acts.

Getting started

2 min

What to install, what is optional, and what to read next.

One recording, seven acts

The second half follows a single block-design motor task. Moving the left hand should raise HbO and lower HbR over the right hemisphere, and the right hand over the left. Every stage should agree.

Channels
51, at 2 wavelengths
Sampling rate
~5.09 Hz
Duration
316.5 s
Conditions
Rest (10), left hand (4), right hand (4)
  1. Open and look Info, channels, the raw time series and the frequency plot
  2. Preprocess Optical density, TDDR, band-pass and Beer–Lambert in Cedalion
  3. Name the conditions, check the channels Quality control writes the bad-channel record
  4. Block average Left hand against right, on the contralateral side
  5. Fit the GLM Canonical HRF, AR-IRLS, and the t-map on the cortex
  6. Onto the head Optional: forward and inverse model on the Colin27 atlas
  7. Save it, all of it Export with the record, save the project, reopen it
