Bug #57
closedBug #80: Version 1.6 bugfixes
dbconvert doesn't get detector sizes right?
Description
Looks like it converts these old-format data
Half of X, half of Y, full Z sizes (in m) of S1 0.88 0.18 0.005 - Meters
to these in the corresponding new-format database
L.s1.size = 0.88 0.18 0.01
Something is obviously wrong. The z-value needs to be 1/2 of what it is.
For consistency, we might also want to store full x and y sizes in the database. Internally, we can divide them by 2 and work with half-sizes.

A little debugging revealed that all new v1.6 databases need to specify detector dimensions as "full" sizes. v1.5 and earlier databases defined the x and y size as "half" sizes, while z was full size. dbconvert simply copied the size values without any modifications, which was incorrect. I fixed this in commit 48849d8. So that was definitely a bug.
However, I could not reproduce the problem described in the description of this issue. The z-size is always correctly copied. Maybe this was a rounding problem due to a leftover output stream state. Since I can't reproduce it, I have to assume it got fixed as a byproduct of further code development. So let's close this issue for now, but keep a note to self to continue checking the dbconvert results carefully as we do further testing.
