[Homer-users] Possibility to export raw data after preprocessing?

[Jahani, Sahar]

Dear Laura,

You can apply bandpass filter on the raw .nirs data, but the input of hmrMotionCorrectWavelet.m is OD. As far as I know, writing a code as follow may help:


1)     load "file name".nirs  -mat

2)     y=d; % d is raw intensity signal

3)     fs=1/(t(2)-t(1));

4)     [y2,ylpf] = hmrBandpassFilt( y, fs, hpf, lpf )

5)     dod=y2;% replace dod with raw intensity signal and then feed it to hmrMotionCorrectWavelet function

6)     [dodWavelet] = hmrMotionCorrectWavelet(dod,SD,iqr)% here, the output is the raw intensity signal after being processed by bandpass filter and wavelet motion correction


Hope this will help,
Sahar

Dear all,



I was wondering whether there is an implemented possibility to export the raw nirs data from Homer after preprocessing (e.g. wavelet correction and bandpass filter) before converting the raw signal to OD or concentration changes?

Thank you very much for a reply already in advance!

Kind regards,
Laura
