Hi, I'm new to Homer3 and working my way through training tutorials. I've made it to the stage of generating the group results output file and can visualize the average HRF. However, when I tried to run the displayStats.m function I was unable to open it (error message attached). I couldn't find this function in my Homer3 master folder - Is this a separate function I need to download/install? Note: I'm using a PC with Matlab 2021b. By the way, my programming experience is with LabVIEW so I'm still very new to the matlab environment - this may be a very simple fix that I didn't spot. Thanks. Dave

I am not familiar with the displayStats() function. Did someone add this to Homer? Where did you learn about this function?

Hi David.

This function was presented during one of the Homer Premium training courses, FNIRS COURSE – DAY 5 – NOVEMBER 15, 2021 Day 5 GLM with tCCA 2021 by Dr. Meryem Yucel.
displayStats.m was a function used starting around 1:23 mark in the video.

Here's the basic description along with an explanation of the parameter options:

displayStats (filename, Hb, p-threshold, flag-contrast)
filename: name of the homer output file, including .mat extension
Hb: (1) HbO; (2) HbR; (3) HbT
p-threshold: pthreshold for paired t-test stats
flag-contrast: (1) contrast stats (0) baseline vs. condition

The result from running this function was a table output
Source #/Detector#/tval/pval

 

It seemed like a very useful function during her presentation, so I was hoping to try it out. Thanks. Dave

Hi Dave,

 

This is not a homer function, so will not be under homer directory. I am happy to share it with you, if you send me an email.

 

Best,

Meryem
