BME680 conversion from sensor resistance reading to gas concentration

Hello,

we integrated the BME680 sensor into our new prototyping board. I managed recover all the mesurement done by the sensor, i can process almost all except the gas resitance reading. With this mesurement i have the resitance reading from the  sensor but i don't know how to convert it into a VOC concentration.
Is there a calculation i can apply to my resitance reading to deduce the concentration ?

Thanks in advance for your help.

Unlike the raw sensor output (gas resistance) that can be obtain directly from the sensor via the compensation formulas, you will need to integrate the BSEC library (pre-compiled binary available here) to transform the gas resistance values into IAQ index (or any of the other available processed outputs).
