In cases where two or more sequences are sampled with equal abundance, FASTAptamer-Count follows standard competition ranking (e.g., “1-2-2-4” where two sequences are tied for second). READS is the raw number of times a sequence was counted. RPM is “Reads per million,” which is a normalized value that allows for comparison across populations of varying read depth. RPM is calculated as: RPM = (READS/(population size)) x 10^6. + +------ + +.. image:: + http://burkelab.missouri.edu/images/fastaptamer-logo-xs.png + :height: 98 + :width: 300 + +For more information on FASTAptamer, visit our website_. + +FASTAptamer is distributed under a GNU GPL v3.0 license.
