Arelle locate ratio extraction command that i cannot understand to find in docs(~2pages)

Question

The basic command while we are working with Command Line Operation in Arelle is:

python arelleCmdLine.py arguments

provided we go with the cmd to the folder that arelle is installed.

I have devoted huge resources but i cannot find if there is a command in the Documentation (about ~2 pages) that can output ratios (e.g. Current Ratio) or metrics (e.g. Revenue) instead of having to download all the data in Columns and filter the data. I must admit that i cannot understand some commands in the documentation.

What i am doing to download data is:

python arelleCmdLine.py -f http://www.sec.gov/Archives/edgar/data/1009672/000119312514065056/crr-20131231.xml -v --facts D:\Save_in_File.html --factListCols "Label Name contextRef unitRef Dec Prec Lang Value EntityScheme EntityIdentifier Period Dimensions"

• -f is the command that pulls data and after that is a location with data in the web
• -v is the command to validate the data that are pulled
• --facts Saves the data in an HTML file in a designated directory
• factListCols is the Columns i choose to have (i take all the available columns in the upper command).

There is an absolute zero on tutorials.

Arelle only runs on Python 3 and can be downloaded without creating a hassle only by following these quick and simple steps.
