[Homer-users] Error while running Homer2_UI with hmrMotionArtifact

[Charlotte PIAU]

Dear Homer users,

I have attempted conducting analysis with Homer2_UI for my several fNIRS data with the aim of removing artifacts and calculating HRF. Before the Homer2 analysis, the data had been converted successfully to .nirs.
However, when I defined values in the "ProcessOpt functions" and ran the analysis, I obtained, for only one file,  an error message that was popped up as below,
"Error: Function hmrMotionArtifact generated error at line 72: fs must either be "sample frequency or a time vector with same length as d"

I looked at various options in Homer2_UI to sort out this issue but they were unsuccessful. I even tried the solution proposed by Meryem (https://mail.nmr.mgh.harvard.edu/pipermail//homer-users/2017-June/001027.html<https://mail.nmr.mgh.harvard.edu/pipermail/homer-users/2017-June/001027.html>) but my raw signal has not negative values.

You can find it on https://mega.nz/#!6YxzHJzR!QNclxRL_68XMDhZchs5a78ksU3-fVPM5joUBpuMQSPY

So, it would be highly thankful if you could provide a feasible solution to overcome this issue.
Looking forward your assistance.

Thank you
