Unexplained Repeated Pregnancy Loss is Associated with Altered Perceptual and Brain Responses to Men’s Body-Odor

functional:
Each subject has two functional scans, separated by T1 anatomical scans.
Each functional scan started with a 4-sec emotional clip (to be excluded in the analysis as in the preprocessing we skip the first 8 TRs),
and next 12-sec-long video clips were presented: 20 clips of high emotional content and 20 landscape clips, in alternating order, with an ITI (fixation point) of 8-12 sec. Following each video clip, participants were asked to rate their emotional arousal, on a scale of 1 to 8, with 8 being the highest. Simultaneously with each video clip, body-odor or blank were delivered using a computer-controlled air-dilution olfactometer that embedded the odorant pulse within a constant stream of clean air at 1.5 liter per minute.
The two functional scans were identical except for the odor content.
The two conditions (blank vs. stranger body-odor) were counterbalanced for order between participants.
Participants were aware of the possibility of an odor being delivered, but were not told when.

In 4 subjects, the last event was excluded as the scan duration was too short: (total 39 events):
sub-07 run1 trim: 4 Tr, total 442-4=438 TRs.
sub-07 run2 trim: 5 Tr, total 442-5=437 TRs.
sub-52 run1 trim: 4 Tr, total 442-4=438 TRs.
sub-34 run1 trim: 4 Tr, total 442-4=437 TRs.

In sub-35 run2 due to technical problem, script stop before the last 4 events: 2 emotional and 2 landscape, thus include total 36 events, trim: 60, (total 466-60=406 TRs).
