Data quality . For the users of an atlas it is important to find information on the quality of the data they retrieve . Atlases based on first party material , have protocols for data creation . The GENSAT website provides protocols for the generation of reporter mice and for the applied histological procedures . Similarly , all standard operating procedures are available on the GUDMAP website . The GEISHA website gives the protocols for their high throughput project . For XGEbase the information on how experiments were performed is described in a publication ( 23 ) .
