Do I need to trim DNA SMART ChIP reads prior to mapping?

You should trim three nucleotides from the 5' end of your reads (Read 1). Optionally, you may also trim Illumina adapter sequences and stretches of poly(T), particularly if you read more than 50 nucleotides, as sequences from short inserts will contain the T-tail that is added in the library construction process.
