6.1 KIDA utility
Warning: now superseded by DOCMAKE
A nice utility is included in Krome to consistently convert the KIDA (reaction database) format as downloaded from their website (http://kida.obs.u-bordeaux1.fr/, requires login) to a format readable by KROME. You can use it to select different reaction rates based on elements/physical processes and other options. The options can be modified in the preamble of tools/subkida.py file. Note that this utility is for testing purposes only; to produce a correct reaction network the reaction rates should be carefully checked. Unfortunately, the probability of making some mistake is quite high...
The python script has the following selection criteria:
#list: atoms to avoid, e.g. avoid = ["C","O"] skips carbon-based and oxygen-based species. # when empty skips no atoms. "e" is the electron. avoid =  #list: atoms to use. e.g. use = ["C","O"] uses only carbon-based and oxygen-based species. # when empty uses all the atoms. "e" is the electron. use =  #integer: maximum atoms per molecule maxatoms = 999 #boolean: use cations (+) ions = True #boolean: use anions (-) anions = True #float: minimum and maximum temperature Tmin = 1. Tmax = 99999. #list: species to be excluded, e.g. exclude = ["CO","C"] exclude CO and Carbon. # when empty include all the species exclude =  #list: exclude species that contain a specific case-sensitive string. # e.g. exludein = ["l-"] excludes linear molecules. can be empty excludein =  #boolean: include multiple reactions (same reactants and same products). # this is useful to skip coefficient from different references. # very dangerous since it employs only the first reaction found. multiple = False
