Note: RWT = rhodamine WT; dye used in the study

Code folder:
* all code are written in the MATLAB language and can be processed in MATLAB or Octave
* The .m files (also available in .txt format) can be opened with common text editors like Notepad.


Processing fluorescence data from aerosols sampled into liquid.

1. run Pend_CSIDE_RamAreas_ScanToNFList.m

It uses as inputs:

*Pend_CSIDE_Ramans.txt ; also available as Pend_CSIDE_Ramans.csv
- correction factors for fluorescence intensities at excitation wavelengths given in column 1 for each time a Raman correction was run (each time instrument was ran). Row 1: corresponding data file name. Row  2: gain (medium or high). Column 1: wavelengths. Column 2: correction factors for given wavelengths and gain for given day

*RamanIntegrationRange.m 
- by K.R. Murphy
- MATLAB code; can be opened in text editors

And produces:
Pend_CSIDE_RamanAreas.txt ; also available as Pend_CSIDE_RamanAreas.csv
- included; so above can be skipped


2. run: Pend_CSIDE_ReadEEMs.m
- This takes the fluorescence data from each scan of each sample ...
  - does the background correction ...
  - takes the average of the 3 scans ...
  - to generate the average, background corrected fluorescence intensity

inputs:
Pend_CSIDE_RamanAreas.txt ; also available as Pend_CSIDE_RamanAreas.csv
- Raman normalization values


3. Run or read & reproduce the calibration code: Pend_CSIDE_CalCurve.m



Applying the calibration curve to the fluorescence data generates the concentration of RWT in each liquid sample. The data are in:

folder_scan_Fluor_PPB_2019mar19.mat

- contains the 39x4 cell scanAVGs7 ...
(The file contains just that cell but they don't have the same name.)
... 
 - 4 variables in 4 columns:
   1. data folder name (gives the date sample was collected & ran)
   2. the name of the data in the EEMs Folder corresponding to that sample
   3. fluorescence intensity
   4. RWT concentration in ppb in the liquid sample from calibration curve.

I also converted it to CSV: folder_scan_Fluor_PPB_2019mar19.csv
