pattern	required?	description
extras\/.*	✓	Folder for general lab-specific files related to the dataset. [Exists in all assays]
extras\/microscope_hardware\.json$	✓	[QA/QC] A file generated by the micro-meta app that contains a description of the hardware components of the microscope. Email HuBMAP Consortium Help Desk help@hubmapconsortium.org if help is required in generating this document.
extras\/microscope_settings\.json$		[QA/QC] A file generated by the micro-meta app that contains a description of the settings that were used to acquire the image data. Email HuBMAP Consortium Help Desk help@hubmapconsortium.org if help is required in generating this document.
raw\/.*	✓	This is a directory containing raw data.
raw\/images\/.*	✓	Raw image files. Using this subdirectory allows for harmonization with other more complex assays, like Visium that includes both raw imaging and sequencing data.
lab_processed\/.*	✓	Experiment files that were processed by the lab generating the data.
lab_processed\/images\/.*	✓	This is a directory containing processed image files
lab_processed\/images\/[^\/]+\.ome\.tiff$	✓	OME-TIFF file (multichannel, multi-layered) produced by the experiment. If compressed, must use loss-less compression algorithm. See the following link for the set of fields that are required in the OME TIFF file XML header. https://docs.google.com/spreadsheets/d/1YnmdTAA0Z9MKN3OjR3Sca8pz-LNQll91wdQoRPSP6Q4/edit#gid=0
lab_processed\/images\/[^\/]*ome-tiff\.channels\.csv$	✓	This file should describe any processing that was done to generate the images in each channel of the accommpanying OME TIFF. The file should contain one row per OME TIFF channel. Two columns should be booleans “is this a channel to use for nuclei segmentation” and “is this a channel to use for cell segmentation”.
