Just download or clone the repo and run 'npm install' to install the dependencies (Papaparse and NWJS), then run 'npm start'.
Available in the "Releases" side menu
Ira expects .csv or .txt files, so you cannot load the data files exported directly from your spectrometer (.sp, .spc, etc...) as generated by the machine without first exporting to CSV or ASCII text.
Sometimes if you get an error while it's trying to load that's because the csv file has some metadata it didn't expect, it does its best to clean it but if that doesn't work out you can help it out by trimming anything that isn't x,y coordinates.
Sometimes the peak detection tool will throw an error when trying to detect the peaks of stacked spectra plotted as %T. This issue occurs if you stack using +Stack for spectra acquired in transmittance. Stacking transmittance spectra is recommended by using the -Stack button.
