Processing S3A_SR_1_SRA data

Hi
I downloaded Sentinel 3 data . It worked very well for the same date using : Sentinel 3 OLCI level 1 and 2 data
S3A_OL_1_EFR_, S3A_OL_2_WFR

BUT
for S3A_SR_1_SRA data I could not work with the files after unzip:
xfdumanifest.xml. acquisition.nc, measurement.nc

Is some one has processed SR data to help?

Thank you
