WALTER (Web-based Analyser of the Length of Telomeres) is a web-based toolset for terminal restriction fragments (TRF) scan analysis. It is consisted of two tools: ScanToIntensity and IntensityAnalyser. ScanToIntensity tool is able to convert selected areas of TRF scan into intensity profiles while IntensityAnalyser tool analyses the resultant file from ScanToIntensity to provide a boxplot or a violin plot depiction of said profiles with a possible statistical analysis.

WALTER toolset is running on the servers of Core Facility Bioinformatics, CEITEC. Toolset development was supported by the Czech Science Foundation, project no. 18-07027S.
