pattern	required?	description
extras\/.*	✓	Folder for general lab-specific files related to the dataset. [Exists in all assays]
extras\/.hardware\.json	✓	JSON file containing the machine parameters/settings. This is akin to the microscope_environment.json file that’s used to describe the imaging equipment.
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.
raw\/images\/[^\/]+\.mcd	✓	Proprietary data file format generated by the Fluidigm (Standard Biotools) Hyperion series instruments to store imaging mass cytometry data. This file contains xyzc pixel intensity values, pre- and post-ablation panoramas, and acquisition metadata. Tools to read are https://github.com/BodenmillerGroup/readimc and MCDViewer https://www.standardbio.com/products/software#hyperion-anchor. No public schema is available.
raw\/images\/[^\/]+\.tiff	✓	Raw image file.
raw\/images\/tiles\.csv	✓	This file contains the approximate coordinates for each of the tiled raw images.
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 provides essential documentation pertaining to each channel of the accommpanying OME TIFF. The file should contain one row per OME TIFF channel. The required fields are detailed https://docs.google.com/spreadsheets/d/1xEJSb0xn5C5fB3k62pj1CyHNybpt4-YtvUs5SUMS44o/edit#gid=0
