Dear FreeSurfers,

Recon-all exits with the following error

ERROR: input(s) cannot have multiple frames!

$SUBJECTS_DIR/Barba50527_2/mri/orig/001.mgz has 439 frames

If I open 001.mgz using freeview, I obtain the image in the attachment saved as freeview 001.mgz.png. 

In order to make sure that my problem does not come from further upstream, I am including the major steps that I took to get to this error.

STEP0: 

My inherited data has names

BARBA50527.MR.MEDITATE_MEDITATION.#.#.year.month.day.#.#.#.#.#.IMA

where each # is a string of numbers. 

STEP1: 

The images can be grouped into five categories, according to the numbers in the names that occupy the positions of the red #:    1.1-1.3,    2.1,   3.1-3.160,    4.1-4.439,    5.1-5.439 

[1] Note: Images from groups 4 & 5 are very different from the images of groups 1, 2 and 3. An example of each is included in the attachment.
