[HCP-Users] Time series data

2018-12-19 Thread Rakib Al-Fahad (ralfahad)
Hello All, I want to analyze time series data and dynamic brain connectivity from rfMRI data. I don’t want to use ICA based time series because they cannot answer lot of neuroscience question. I prefer ROI based analysis. A 45+ ROI template would be useful (e.g. FreeSurfer template). Is it

What neuroscience questions are ICA timeseries unable to answer? Particularly that gyral/sulcal folding-based parcellation would be able to answer? If you want a neuroanatomical parcellation into cortical areas, this is available here: https://balsa.wustl.edu/file/show/3VLx Matt. From:

Matt, I agree with your pint. My specialization is in signal processing and machine learning. I am not sure about ICA based time series. If we consider 100 ICA components, how can we define each node name for graph theoretical measures? For example, the paper ‘Chronnectomic patterns and

Hi Manasij, We’ve discussed this in some detail with the folks at FMRIB. They have long known that the cost function in FLIRT (and MCFLIRT) is biased toward zero for very small motions. However, when the movement regressors have long series of zeroes, the motion corrected time series does not

We generally do use timeseries for single-subject analysis. The only involvement of ICA there is in cleaning up things like artifacts - think of it as using ICA to identify nuisance regressors. The end result is still a timeseries, but with greatly reduced artifacts. You can use wb_command
