Updated loadHitachiText.m

Some labs have been using our script readHitachiData.m to load NIRS data from Hitachi ETG machines. We recently found that some output MES data contains abnormal timestamp. For example, the timestamp should be like 16:49:25.406 But for some rows (alt

Chin rest (head holder) device for NIRS

When we set up our NIRS lab back in 2008, we needed a device to prevent participants’ head movement during the experiment and during the digitizer measurement. Even though NIRS is tolerant to head motion, we still want to minimize it. During th

We contributed to MatLab (wavelet toolbox)

We use MatLab a lot! It’s the major program for brain imaging data analysis in our lab. However, I never thought we could actually contribute to MatLab’s development. In MatLab 2016, there is a toolbox called Wavelet Toolbox. If you read

A mistake in my False discovery rate (FDR) correction…

I have posted an FDR script at https://www.alivelearn.net/?p=1840. I noticed that there is a small bug. In rare cases, this bug will cause the most significant voxel to be classified as ‘non-significant’ while other voxels are ‘sign

OpenBCI EEG

Manish Saggar in our lab brought something very cool – a helmet like EEG system. He called it “dry” EEG because it does not requite gel. The design is not polished, but it’s cheap, like $800. And it does not need long wires to
