Dear all,

I would like to ask your help in interpreting OME TIFF metadata: Could you tell me please how to determine the units of time based on metadata?

Thank you for any input, Best regards, Aliaksei

Hi @aliaksei-chareshneu, the units should be determined by the DeltaTUnit value on the Plane element such as below. By default this should be seconds but it will depend on the software which created the metadata originally.

<Plane DeltaT="4950.364303196173" DeltaTUnit="s" ExposureTime="1.0366783402636648" ExposureTimeUnit="s" PositionX="277.7" PositionXUnit="µm" PositionY="1282.2" PositionYUnit="µm" PositionZ="2119.4" PositionZUnit="µm" TheC="0" TheT="0" TheZ="0"/>
