`min_analyte`	a int that specifies the minimum of analytes the pathway should have to be considered compute for overlap matrix
`overlapmethod`	a string that specifies the way to compute overlap matrix, must be 'balanced' or 'weighted'
`together`	a boolean value to compute overlap matrix for gene/metabolites separatly or together
`conpass`	a string that specifies password for database connection
`host`	a string that specifes host for database connection
`dbname`	a string that specifies database name of MySQL database
`username`	a string that specifies name of MySQL database
