The present study has examined plasma metabolomic components with molecular weights < 1.5 kDa derived from rats with induced retinopathy in high oxygen concentrations in order to seek potential biomarkers for retinopathy of prematurity (ROP). Metabolite information were showed in Metabolome_data.csv and SampleInfo.csv. A total of 122 metabolites were annotated. Detailed information were listed in Metabolite_annotation.csv.
The file contains the MATLAB (MathWorks) code that was used to obtain the A-scan ultrasonography-matched refractive indices.
To replicate our fitting, save the MATLAB file and the data file in the same folder and follow the instructions given in the MATLAB file. To obtain refractive indices for different species, change the sound velocities in the MATLAB file according to your species and generate a new data file. If your ultrasound measurements do not resolve CT and ACD, follow the column structure of our data file. If you have separate ultrasound time delays for CT and ACD, generate a data file with the following columns from left to right: OPLs of CT, ACD, LT and VCD followed by ultrasound time delays of CT, ACD, LT, and VCD. In our MATLAB code, we assume that CT and ACD can (cannot) be resolved form the ultrasound measures if the number of columns of the data file is even (odd).
