error during calibration

[hanhanhan-kim]

Hello, I've been having an issue running the anipose calibrate command. I am using a Conda environment that can run DeepLabCut, on Ubuntu 18.04. When trying to run anipose calibrate I get the following error:

(dlc-anipose) hank-x299@hank-x299:~/src/dlc-utils/examples/beetlepose$ anipose calibrate

My config.toml file looks like so:

project = "beetlepose"
path = "/home/hank-x299/src/dlc-utils/examples/beetlepose"

nesting = 1

video_extension = "mp4"

# regex matches 8-digits proceeding a "_":
[triangulation]
cam_regex = "guid_[0-9]{8}"

[calibration]
# checkerboard / charuco / aruco
board_type = "checkerboard"

# width and height of grid
board_size = [6, 6]

# length of marker side
board_marker_length = 0.3 # mm

# If charuco or checkerboard, square side length
board_square_side_length = 0.3 # mm

animal_calibration = true

Given the above, why might I be getting IndexError: tuple index out of range? Thanks!

Solved: I needed to modify the cam_regex as follows: cam_regex = "guid_([0-9]{8})"

Perfect, thank you for posting this issue and the solution!
