If it is Hitachi, I have written a script to convert the output csv file (the raw probe one, not the chromophore ones) into a. Thanks and looking forward to your replies. nirs files for use with Homer2?Īlso, one more question: when I was collecting the data I was not very knowledgable about NIRS and I therefore assumed that a sampling period of 0.5 seconds would suffice? Do you think that this sampling rate is way too low? My question is therefore the following: from your experience using the ETG-4000 can I use the matlab script you so kindly prepared to convert these MES. csv file containing the raw intensity data. So it seems that when using Integral Mode, the exported data includes a. csv file with the tag MES, which I just got to know stands for measurement data. csv files (tagged HBA) containing concentrations for oxy, deoxy and total Hb, I have a. ![]() But I have noticed that for each subject, together with the. csv files I exported from the ETG-4000 are rather useless in this case. Now I am aware that Homer2 does not allow one to import concentration files - one must have files with the raw data. I analysed the data on the device itself in Integral Mode. I collected data using a Hitachi ETG-4000. Sorry I can't be more help there.įrom: Marco Montalto I would have thought that 0.5s was acceptable given that fMRI provides sampling rates of 1 to 2 seconds but I guess it depends what you're looking at. sampling rate on our machine is fixed to 0.1s and I don't think we can easily change it. This is correct, my script is designed to take the MES file (in csv format) and convert it to nirs format. nirs file and Sample Data Rebecca Dewey Rebecca.Dewey at nottingham.ac.uk ![]()
