Quick start

To make images with IDG one can use WSClean in IDG mode. To make this mode available build the IDG library before building WSClean and make sure the IDG library can be found when compiling WSClean. WSClean can then be invoked like this

wclean -use-idg -size 1024 1024 -scale 10asec -idg-mode [cpu/hybrid] example.ms

To learn how to use IDG as a component in your own software the quickest route is to look at the Python demo. To run the python demo the IDG library needs to be built with python support and demos

cmake -DBUILD_WITH_PYTHON=ON -DBUILD_WITH_DEMOS=ON
make
make install

The demo needs a measurement set. An example measurement set can be downloaded from https://support.astron.nl/software/ci_data/IDG/MWA-1052736496-averaged.ms.tgz
