Hello,

Thanks to Jim B for the pointing to the most efficient option for the storage Block size needed declared on part D of the pathname: monthly block is the best for 15-min to 12-hr data. As for the 2nd line of the ASCII file, both formats are equally correct & acceptable.

And Yao, I have no problem at all in 'viewing' your full set of data (each series contains 43801 data values = 43800,2-hr intervals =3650 days ~ a decade) --- I use a quite handy utility called DSSVue for just viewing and/or editing DSS files. If you can not 'view' your full one decade of data (outside RAS) then you might have some problems with setting the correct Start Date & Time and/or with the other parts of the pathname; Jim's cautionary remarks should be taken seriously. And when you finally pass this stage and are sure that your data are correctly transferred into a couple of DSS files, you may then want to take a look at the HEC-Users archive : some colleagues believe that the present version of RAS (v.3.0.1) has serious problems in importing DSS files.

Hope the RAS is kind to you and to your particular case.

Best of Luck!
