Data collection techniques

Definition

Data collection techniques are systematic methods used to gather information and insights about a particular subject or phenomenon. These techniques can vary widely depending on the field of study and the specific objectives of the research, often influencing the quality and validity of the resulting data. In the context of time-resolved crystallography, these techniques are crucial for capturing dynamic structural changes in biomolecules and materials over time.
