gdxcompare
Purpose
Tool to compare symbols in GAMS Data eXchange (GDX) files with time series data (specifically integer indexed data).
Usage
After installing the module, just call
python -m gdxcompare [options] gdx1 gdx2 ...
An HTML page will open up, showing something similar to this screenshot.
- Symbols (variables, parameters) are listed on the left and are selected by left clicking.
- Set dependencies and corresponding elements are listed in adjacent columns. Set elements are selected via mouse hovering.
- The color of the cells indicate the relative variance across elements in a set, so that blue elements will exhibit smaller differences across GDXs than red elements.
- The time series of the queried data is shown on the right. A title reports the description of the selected symbol and the last element selected. The time axis is identified as the first set with integer elements.
- Zooming is supported via horizontal or vertical mouse dragging. Mouse hovering provides details on the top right corner.
Requirements
- Python (tested with Python 3.6).
- up-to-date numpy module.
- up-to-date gdxpy (requires manual installation from github).
Options
Options
| Short version | Long version | Description |
|---|---|---|
-h |
--help |
Show this options list and exit |
-m XMAX |
--xmax=XMAX |
Max value for x-axis [0 = no max, default] |
-f XMIN |
--xmin=XMIN |
Min value for x-axis [0 = no min, default] |
-r RENAME_STRING |
--rename=RENAME_STRING |
Comma-separated list of new names to give to GDXs (no spaces) |
-s SYMB_REGEX |
--symb=SYMB_REGEX |
Regex for filtering symbols, or lambda starting with @ (e.g. @len(x)<5 for all symbol names shorter than 5 characters) |
-p PROF |
--profile=PROF |
Profile name, used if no SYMB_REGEX specified, associated to a predefined combination of regex for filtering symbols (see here for examples) |
-x LAMBDA_EXPR |
--xlambda=LAMBDA_EXPR |
Lambda function applied to each element of the x-axis |
-d |
--disaggsymb |
Flag to disaggregate large symbols across elements of the first domain |
For example:
python -m gdxcompare -sQ -rbau,ref -m20 results_bau.gdx results_ref.gdx
will compare symbols starting with Q of the two GDX files results_bau.gdx and results_ref.gdx in the current path, labelling them as bau and ref, and showing results up to period 20.
