This data supports the publication: "The role of late
photons in diffuse optical imaging" and can be found at:
https://doi.org/10.1364/OE.402503

All codes are MatLab (".m") format and all raw data files
are ".mat" format.
 _______________________________________________________________
|***IMPORTANT***						|
|These codes were built using MatLab version R2020a. The 	|
|function "multissim.m" was only introduced in version R2020a	|
|and hence this is a minimum version requirement to run the 	|
|codes. 							|
|More details of the function can be found at: 			|
|(https://uk.mathworks.com/help/images/ref/multissim.html)	|

The main image retrieval algorithm is named
"CDI_main_SD_latephotonsDOI.m" and is a modified version of previously
published code: (http://researchdata.gla.ac.uk/642/).
This code has comments explaining use in the first 21 lines. 
This code uses functions from the folder "tools" and pre-processed raw 
SPAD data from the folder "data". The data used in this work is also
taken from the work in (http://researchdata.gla.ac.uk/642/).

The code and data used to make the figures for the published paper
can be found in the folder "figure files". Matlab code and associated 
files to produce all figures showing results in the published paper are
contained in this folder, there is one MatLab code file for every figure.
 _______________________________________________________________
|Note: the matlab file "fig4_full_scan.m" calculates metrics 	|
|and plots a full scan of temporal data with corresponding	|
|retrieval. The published figure uses the data produced in 	|
|this code but is represented differently.)			|
|_______________________________________________________________|

Full parameter scans can be found in the folder "parameter scans". 
The main files are "metrics.m" and "metrics_X.m" which show early/late/all
parameter scans with associated metrics taken from the raw data contained
in the folder "scan_data". The folder "all_data" contains the raw files 
("raw/...") and pictures of the full scans for all tested cropping windows 
("all_scans/...").All raw data, from every parameter scan can also be 
found in a sub folder along with .png imagesfor quick viewing of the 
results and a summary document
"The_role_of_late_photons_in_diffuse_optical_imaging__Supplementary.pdf".
