Log File

Except for the spinning emoji and the program progress messages, all the terminal output is written in the log file and saved in the current working directory. The log file also includes the time and the log status.

By default, the SEGUL log file is named segul.log. SEGUL does not overwrite the log file. Each time you run the app, if the log file exists in the same working directory, it will append the log output to the same file. You can customize the log file name using the --log option, which is available in all features.

For example, to set the log file name for alignment concatenation:

segul align concat -d alignment_dir/ --log my_log_file

Below is an example of the terminal output as of v0.21.3:
