Table 3 Overview of known data acquisition anomalies (F: functional data, P: physiological recordings during fMRI session, S: structural data).
From: A high-resolution 7-Tesla fMRI dataset from complex natural stimulation with an audio movie
Modality | Participant | Segment | Description |
---|---|---|---|
F | 4 | 8 | due to an image reconstruction problem, the last 75 volumes for the last movie segment are missing |
F | 4 | 5–8 | motion caused by the participant coughing occasionally |
F | 10 | 1–8 | distortion correction invalid: only non-distortion-corrected fMRI data available |
F | 11, 13 | 3, 4, 7, 8 | both participants show significant motion due to physical discomfort in the last two segments of both recording sessions (first session in particular); see also Figure 4b |
P | 1, 2 | 1–8 | recorded at 100 Hz, some intermediate trigger pulses |
P | 18 | 1 | where not detected and have been interpolated |
P | 4 | 1–4 | suboptimal data quality – hand with pulse oxymeter sensor was positioned on the participant's stomach and affected by breathing motion |
P | 7 | 1–4 | pulse oxymeter repeatedly reported bad signal quality |
S | 2 | due to a data IO error 13 slices of the angiography scan are lost (image usable but smaller FoV in Z-direction) | |
S | 6 | FoV of the angiography scan had to be enlarged to prevent fold-in effects |
