We collected cerebral blood flow data in the prefrontal cortex using the HOT-2000 device, but the data we collected was in a CSV file. We also intend to analyze the data by Homer3. How can we convert the CSV file data to an NIRS or SNIRF format?

Dear Kecheng,

I am not familiar with the HOT-2000 format, but I would try using SNIRF MATLAB writers, (assuming you have access to MATLAB). First, you can use csvread to read a CSV file, then use one of the proposed parsers. 

Have you tried to contact the manufacturer technical support? Sometimes they have conversion libraries that can be shared with their customers.

@codina Thank you for the information. I converted the CSV data to .nirs data and then automatically converted it to .snirf format.

I have used this script: https://www.nitrc.org/projects/hitachi2nirs

 

However I am having trouble converting the .nirs files that I got from this script to .snirf files in Homer3. Anyone else having this issue?

Just curious, but what errors do you get?
