Using the GUI and CLI

GalMEx can be used through two user-friendly interfaces:

• Graphical User Interface (GUI): for interactive visual configuration

• Command-Line Interface (CLI): for automated or batch processing

Launching the GUI

The GUI is the default interface. Simply type:

galmex

This will open a graphical window where you can:

• Select image folders and configuration settings

• Enable/disable modules like CAS and MEGG

• Preview parameter values

• Run the pipeline with progress and live feedback

Using the CLI

To run GalMEx non-interactively using a configuration file:

galmex path/to/config.json

You will be prompted before overwriting existing output files. All results and logs are saved automatically.

CLI features include:

• Detailed logging to results.log

• Automatic handling of output file naming

• Parallel processing using the cores setting in the config

• Identical results to GUI-based runs

Logging and Output Files

Both GUI and CLI modes produce:

• A CSV output file (default: results.csv)

• A log file (e.g., results.log)

• A copy of the configuration used (e.g., results.json)

Logs include a line-by-line status for each processed galaxy:

Starting to process galaxy 587725470138171560...
587725470138171560 completed successfully.
587725470138237021 failed: background estimation failed.
