Scid outputs this analysis of a PGN file using the Stockfish engine:
What does the
D mean? And where (e.g. a web page) is this actually explained?
This is a special mark meaning
diagram. When you export the game into a PDF/LaTeX file positions after moves marked with
D are rendered in the document.
The only documentation I've found is https://sourceforge.net/p/scid/wiki/HowToExportGames/. Scid vs PC documentation maybe is clearer http://scidvspc.sourceforge.net/doc/Export.htm. But documentation is actually poor, I discovered this feature just testing the
Export to LaTeX feature.
