Example README File
Dataset Title: Raw Images for Experiment A, Smith Lab
Principal Investigator: John Smith, PI, 555-555-5555, jsmith@hms.harvard.edu
File Naming Convention: ExperimentName_InstrumentID_CaptureDateTime_ImageID.tif
The base file name is composed of the name of the experiment, the ID number of the instrument used, the date and time that the image was captured, and the unique identifier of the image.
Attributes: Also see the Codes section for a list of instruments and their ID numbers
- ExperimentName = Name of the experiment
- Instrument ID = Five-digit code assigned to the lab instrument
- CaptureDateTime = Date and time at which the image was captured, in YYYYMMDD format
- Image ID = Three-digit unique identifier for image, such as 001, 002, 003
Codes:
- [List of instruments and IDs]
Examples:
- File formats: daf2-age1_14052_20150412T0515_005.tif
- Versioning: All changes to this dataset will be documented in a changelog in this README file
