==Confusion of high vs. low resolution== | |||
High resolution is characterized by being able to distinguish smaller features, so there is an inverse relationship between the quality of a structure and the length value given for the resolution. For example, a 1.0 Å structure resolves finer detail than a 4.0 Å structure, so the 1.0 Å structure is said to have higher resolution than the 4.0 Å structure. For non-experts, it would be less confusing if the terms were fine and rough resolution rather than high and low resolution, but high and low are the established terms in the field. | |||
