panel_total_bases is calculated by fastp, and column 5 6 7 names is the 0.1 meandepth,  0.2 meandepth,  0.5 meandepth
 
uniform_01 = df.iloc[:, 4].sum() / panel_total_bases
uniform_02 = df.iloc[:, 5].sum() / panel_total_bases
uniform_05 = df.iloc[:, 6].sum() / panel_total_bases

do you think this is not I want
