Analysis scripts
Behavior_analysis.m: for analyses of odor detection tasks (pre-conditioning/Precond, post-conditioning Day 1/Postcond, post-conditioning Day 9/Postcond2) and risk ratings (post-conditioning Day 1/Post, post-conditioning Day 9/Post2)
RSA_analysis.m: for RSA analysis
Phases - PrecEPI1: pre-conditioning; PostEPI3: post-conditioning Day 1; P2EPI4: post-conditioning Day 9
ROIs - r/lapc: right/left anterior piriform cortex; ppc: posterior piriform cortex; ofc: orbitofrontal cortex; amg: amygdala; hip: hippocampus
Odor conditions - cond1: odor1; cond2: odor2; cond3: odor3; cond4: odor4; cond5: odor5
Tuning_shift_analysis.m: for tuning analysis
Behavioral data
/Odor Detection Task contains three subfolders that correspond to data during three different phases: /Pre-conditioning, /Post-Day1-conditioning, /Post-Day9-conditioning
/Odor Risk Rating contains post-conditioning risk ratings: risk1/post-conditioning Day 1; risk2/post-conditioning Day 9
/Respiration contains extracted respiration data (original files too large)
/SCR contains preprocessed SCR data during conditioning
Stimuli
Contains images and sounds used as UCS during conditioning
Images: Neutral (7021 - 7224); Disgust (7301-9354, vomit)
Sounds: Neutral (N1 - N4); Disgust (D6 - D12)
fMRI data
Within each individual subject folder, /beta_matrices_LSA contains .mat data files (e.g. sub1_PrecEPI1_rapc_cond1.mat), which has a "betaMatrix" (15 odor trials X No. voxels) variable of each ROI and odor condition
/coords contains .mat data files (e.g. sub1_lapc_maskidx.mat), which has a "coords" variable that records the MNI coordinates of the selected voxels in the ROI after applying the functional constraint
