[contaminationSearch] Bwa mem configuration causes some misunderstandings in the calculation of the contamination and explodes the CPU quotat of ng6
After several month of bwa meme use for calculation of contamination rate, it appears several problems :
- the calcul of contamination rate is not adapted for what we want to see.
- after a run of NovaSeq we see an large increase of ng6 cPU quota due to the parameters used for launched bwa mem analyzis.
