bug ? NEX-5 raw files and 2 green channels when demosaicking in RD
raw = https://app.box.com/s/k9ykb4cp1dl6lk4316s3i09a0twmoxkw
granted neither RD nor FRW are "raw converters" purpose-wise, but when you do demosaick raw files for a user to view in both apps isn't here a bug related to 2 green channels disbalance for this camera model (at least this one) ? see top - middle part of the frame with zoom > 200% vs other areas
just $0.02

Could you please shot flat

Could you please shot flat gray field using same camera and same lens?

unfortunately not my camera - the matter happened when DXO PhotoLab produced such artefacts and posted this raw... I converted it to DNG using Adobe DNG Converter, altered 0xc62d BayerGreenSplit tag to zero and then Adobe's own ACR too produced similar artefacts in the same areas of the image... ACR does not produce artefacts with 0xc62d BayerGreenSplit = 250 ( that is what their own DNG converter writes in ) ... so one might reasonably assume that it is as mostly happens related to green channels "disbalance" between DN from greens in "blue" rows and in "red" rows
I can ask the owner if he can produce such raws though... will see what he/she says

speaking about green channels disbalance... it seems with X-Trans there is no easy way to see statics per channel ( 4 "green" of them ) in rawdigger, not that maze is an issue for X-Trans demosaicking algorithms used around, but still

X-Trans is 3-channel

X-Trans is either 3-channel or 36-channel
