dataset
posted on 12.09.2017 by Tomas Knapen
Data file contains data for expanded regions of interest. Data types are
1. per-voxel percent signal change time-courses for 6 runs
2. per-voxel percent signal change time-courses for 6 runs, leave-one-out median - name of the array refers to the file that was left out
3. per-voxel percent signal change time-course, grand average over runs (median)
4. parameters of pRF fits per run (leave-one-out)
5. parameters of pRF fits all runs

# indices into prf output array:
# 0: X (position, degrees of visual angle from fixation)
# 1: Y (position, degrees of visual angle from fixation)
# 2: s (size, standard deviation of gauss)
# 3: n (nonlinearity power)
# 4: a (amplitude)
# 5: b (baseline, intercept value)
# 6: rsq
# 7:

The voxel size of these recordings is 2mm isotropic, and the sample duration (TR) is 0.945 s. pRF fits were done using a CSS model implemented in Popeye, using a standard HRF shape.
