Modal mass coefficient and participation factor in Etabs

[franciscomatusm]

Hi. I need to calculate the Modal mass coefficient MMC and participation factors PF of a Building. I know tha in Display > Show Tables I can see the participation factors, but how can i calculate the modal mass coefficients?. I can´t find where can I see the Eigenvectors in Etabs (Modal Shape). If i can find them, then i can calculate the MMC. Thanks
