I uploaded a precomputed version of the bt2 database here: [http://cmprod1.cibio.unitn.it/biobakery4/metaphlan\_databases/bowtie2\_indexes/mpa\_vJan21\_CHOCOPhlAnSGB\_202103\_bt2.tar](http://cmprod1.cibio.unitn.it/biobakery4/metaphlan_databases/bowtie2_indexes/mpa_vJan21_CHOCOPhlAnSGB_202103_bt2.tar)  
Let me know if you have any problems with it
