Datasets on SolveBio are usually populated with clean, processed data. In some cases datasets will be "sparse", meaning that some fields will have a significant number of empty values. This article helps distinguish blank and missing values and explains how to filter them out of datasets.
For most field data types (everything except string and text), empty fields are represented with a "null" value. On the dataset page, open the Filter sidebar, select the field, and choose the condition is not missing, and click Add Filter.
