sub-005 task-C stimuli

Stimuli shown to participant 5 in the training (ses-01) and real-time (ses-03) scans of Real-time Reconstruction of Human Visual Perception from fMRI.

ses-01/participant5_sess1_stimuli.npy, ses-03/participant5_sess3_stimuli.npy: every trial in presentation order, (770, 224, 224, 3) uint8. Blank trials are frames filled with 128 (77 per session), leaving 693 stimulus trials.
ses-0X/participant5_sessX_metadata.csv: one row per trial (same order as the .npy), with run_number, trial_number_within_run, overall_trial_number, is_repeat, is_blank_trial, stimulus_id.
images/: original image files for the 1,000 unique stimuli across both sessions (531 per session; the 62 similar-pair images appear in both). File names match stimulus_id. Native resolutions vary (224–424 px square).

special_* files are from NSD's special515 subset. In each session, 50 of them are shown 3 times (the test set is the 50 from ses-03); ses-01 also shows 210 other special_* images once each.
pair_* files are the 31 pairs of highly similar images, each shown twice per session.
