The article about "rapture sequencing" found here says:
"This protocol also recovers more unique (nonclonal) RAD fragments, which improves both standard RAD and Rapture analysis. Rapture then uses an in-solution capture of chosen RAD tags to target sequencing reads to desired loci. Rapture combines the benefits of both RAD and sequence capture, i.e., very inexpensive and rapid library preparation for many individuals as well as high specificity in the number and location of genomic loci analyzed."
My question is regarding the second sentence. What does it mean to combine in-solution capture of chosen RAD tags to target sequencing reads to desired loci? How do the RAD tags target sequencing reads, if that is what is being said here? How does this relate to combining the benefits of both reduced representation sequencing techniques, or am I missing the crux of the paper?
