Comparison of more than 100 groups!!!


I m conducting an analysis with more than 150 groups of participants (each group corresponds to a week with different number of participants). I would like to find statistical significance among the groups regarding a specific biomarker. Furthermore, i would like to spot the groups (weeks) with the statistically significance. I m using SPSS but i cannot do this for over 50 groups. Does anyone have an idea which is the best way to do in SPSS or to propose me another solution? Thanks in advance!
