Slice timing and motion correction

Project proposals

Presentation of project proposals and feedback.

We discussed modeling the baseline (e.g. fixation) trials, and we looked at the tutorial on correlated regressors.

Teaching

See the diagnostics analysis code for an example of code organization and testing.

• Otsu’s method for binarizing images;
• Correction with the false discovery rate;
• slice timing correction;
• Slice timing exercise;
• how to do slice timing;
• when to use slice timing;
• slice timing artefacts.

Reading and homework

• Rotation in 2D
• Coordinate systems and affine transforms;
• A tutorial on mutual information.
