Beta test users should refer to the 0.7 guide and everyone else will use the indexes from v1.0 While there are similarities to the Truseq adapters, they are not quite the same. Beta users will notice that indexes 1-16 are the same, but indexes 17-24 are different. Version 1.0 has some indexes in common with Truseq, but they do not match up in the same order. In BOTH cases, you'll need to use the Indexes listed on this page for demultiplexing runs.
There is no need to adapter or quality trim the reads generated, since the analysis pipeline used by Prism Portal will include these steps.
