Benchmark Data
This page will contain some 'benchmark' data to be used by everyone assessing the effectiveness of new methods for dealing with the motion problem. There are several datasets that are good candidates to be used as benchmarks. We will need to converge on one dataset, but for now they are listed below:
Subset of Karen and Simon's data: 20 drug users
The advantage of this dataset is that Simon has shown it to display a large motion-related artifact (by reproducing Power et al's cloud plots - see Simon's presentation in 'meeting 1').
The data will hopefully soon be made available (watch this space).
Prantik's datasets
The advantage of Prantik's data is that it corresponds to a single echo extracted from multi-echo data. Any new denoising techniques tested on this will thus be comparable to Prantik's multi-echo ICA denoising. Prantik has provided data for:
- 3 subjects at rest
- 5 subjects watching a movie
- 3 tremor patients
