Hello Sophie,

 

Once this tutorial is fully developed, Can we use this for OCTAMON (https://www.artinis.com/octamon/)  ?

 

Thanks for your understanding and support.

 

Best Regards,

Sunny

Hello Sophie,

 

Thanks a lot for providing this code. I am making some changes that are useful. Can you please inform what is the variable 'data_func' in the code relates to. This is the last undefined variable in code.

 

Thanks for your understanding and support.

 

Best Regards,

Sunny

Dear Sunny, 

 

the multi-channel NIRS data tutorial is currently under construction and will hopefully be fully available in a couple of weeks. Until then, there might still be some inconsistencies such as the one you have encountered.

 

The variable you refer to is indeed missing. It refers to a filtered version of the data, and you can created it by running the following code before the epoching.

 

cfg                 = [];

cfg.hpfilter        = 'yes';

cfg.hpfreq          = 0.01; 

data_flt            = ft_preprocessing(cfg,data_down);

 

This should help you to continue with the tutorial, but please do keep in mind that we are currently working on it and you might encounter some other inconsistencies still later on.

 

Best,

Sophie

Hello All Good Day, 

 

Hope you are doing fine,

 

Thanks a lot for providing with fieldtrip which is really useful to analyze fNIRS data. I have an issue in the "Preprocessing and averaging of multi-channel NIRS data" tutorial. Can you please help me with this issue?

 

Issue: In the  "Preprocessing and averaging of multi-channel NIRS data" tutorial "  <http://www.fieldtriptoolbox.org/tutorial/nirs_multichannel> http://www.fieldtriptoolbox.org/tutorial/nirs_multichannel

 

The "Epoch" section consists of a variable "data_flt.fsample" where "data_flt" variable is not defined. Can you please inform what is this variable related to? as this is needed to complete my analysis. 

 



 

 

Thanks for your understanding and support

 

Best Regards,
Sunny
