PROJECT metadata_update compiler bug 2 #60

Closed marcomass closed 7 years ago

marcomass commented 7 years ago

Bug in PROJECT metadata_update whit ration between two metadata attributes: the calculated ratio seams to be the inverse of what it should be; this does not occur when the ratio is between a metadata attribute and a constant value.

Example query: DATA = SELECT(cell == "Urothelia" AND ID == "40") HG19_ENCODE_NARROW; RES = PROJECT(metadata_update: _id2 AS ID*3 ) DATA; RES_2 = PROJECT(metadata_update: _id3 AS _id2/ID) RES; MATERIALIZE RES_2 into res;

_id3 results 0.33 instead of 3 (0.5 instead of 2 if _id2 AS ID*2).

Conversely, when instead of ID I use its numerical value, e.g., 40, the result is correct: RES_2 = PROJECT(metadata_update: _id3 AS _id2/40) RES;
