[galaxy-user] extension of read length

Dear all, I am working on an MNAse-Seq experiment with 50bp single end reads. To identify nucleosome positions, I read that one needs to extend the single reads to approximately the length of nucleosome protected DNA, being approximately 150bp. Is there a way in Galaxy to extend 50bp reads to 150bp length, lets say from a .BAM file with mapped reads? Of course any other comment on this topic is much appreciated!
