31 This tool is used to select only the uninterrupted microsatellites. Interrupted microsatellites (e.g. ATATATATAATATAT) or sequences of microsatellites with non-microsatellite parts (e.g. ATATATATATG) will be removed.
33 For TRFM pipeline (profiling microsatellites in short read data), this tool can be used to avoid the cases that flanking bases were misread as microsatellite. Thus, the read profile will only reflect the variation of TR length from expansion/contraction.
34 For example, suppose that the sequence around microsatellite is AGCGACGaaaaaaGCGATCA. If we observe read with sequence AGCGACGaaaaaaaaaaGCGATCA, we can indicate that this is microsatellite expansion. However, if we observe AGCGACGaaaaaaaCGATCA, this is more like a substitution of G to A. These incidents can be removed with this tool.
35 You can use the tool **combine mapped flaked bases** to get the microsatellites in reference that correspond to sequence between mapped reads. If the user map these reads around the uninterrupted microsatelites in reference, the corresponding sequences between these pairs should be the uninterrupted microsatellites regardless of expansion/contraction of microsatellites in short read data. However, if the substitution of flanking base or if the fluorescent signal from the previous run make it look like substitution, the corresponding sequences in reference in between the pairs will not be uninterrupted microsatellites. Thus this tool can remove those cases and keep only microsatellite expansion/contraction.
