Quick start#
Once DeLTA is installed, you can already use it without writing any code, with its default configuration, through its command-line interface.
You can read the instructions to use the command-line interface by calling
delta
with the --help
flag:
(delta_env)$ python -m delta --help
usage: delta [-h] -c CONFIG -i INPUT [-o OUTPUT] [--positions POSITIONS] [--frames FRAMES]

options:
-h, --help show this help message and exit
-c CONFIG, --config CONFIG
Configuration file. Can be either `2D`, `mothermachine`, or a
path to a previously saved custom config file.
-i INPUT, --input INPUT
Input file or directory. Can include `{p}`, `{c}` and `{t}` as
placeholders for the position, channel, and frame number.
Example for micromanager: `/path/to/folder/Pos{p}/img_channel{c}
_position{p}_time{t}_z000.tif`
-o OUTPUT, --output OUTPUT
Output directory (by default `delta_results` inside the input
directory)
--positions POSITIONS
Positions to process, ex.: 0-2,4,7-10 (default: all)
--frames FRAMES Range of frames to process, ex.: -150 (up to frame 150), 15-
(from frame 15), 15-30 (frames 15 to 30), 40 (just frame 40)
(default: all)
The only two arguments required are CONFIG
(use mothermachine
if you
are using one, 2D
otherwise, or the path to a config file that you
previously saved), and INPUT
. If your images are saved as a single file,
for example an nd2
file, just provide its name, but if they are saved as
individual files inside a directory, then provide their naming pattern with the
placeholders {p}
for the position number, {c}
for the channel number
and {t}
for the frame number.
Example uses#
You recorded mothermachine images as a
.nd2
file: you can just launch DeLTA on them with
(delta_env)$ python -m delta -c mothermachine -i my_images.nd2
You did an agar pad experiment where each frame is an individual
.tif
image, all saved in the same directoryimages/
with namesposXXX_channelXXX_tXXX.tif
. Then, you can launch DeLTA on them with
(delta_env)$ python -m delta -c 2D -i images/pos{p}_channel{c}_t{t}.tif
