Is this possibly due to anisotropy in the data? ie. data missing in one direction? You can look at the graphs from Truncate to see if this is the case.

However, electron density maps seem 'stretched' in one direction. Data were collected in-house (R-axisIV). Anyone encountered this phenomenon? Thanks!
