HBN double run in filenames: with and without 0

,
1

Hello!

In Healthy Brain Network (HBN) MRI data there are filenames with different ‘run-x’ pattern, specifically:

(1) single run-<1,2,3…>
(2) single run-<01,02,03…>
(3) doubled run-<1,2,3…>_run-<01,02,03…>

image790×1246 206 KB

image874×1242 219 KB

json files between with the same base and run-pattern can be equal or differ in 1 or more params, e.g.:

image
image1800×90 16 KB

image
image2226×368 111 KB

image
image2216×210 54.7 KB

image
image2244×226 59.9 KB

image
image1670×224 64.6 KB

image
image1658×266 75.6 KB

image
image1660×182 38.1 KB

Unfortunately i could’t find information on this in there data notes, and i am super new to MRI data.
Can anyone suggest what could this naming style mean?
BIDS validator doesn’t seem to like it
