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.

Direct connection (calculations might take longer in case more people are using the tools at the same time due to the waiting for other users' process to finish):
- ScanToIntensity tool - tool that allows the transformation of the picture to intensity profiles
- IntensityAnalyser tool - tool that can analyze a file with intensity profiles
Servers might be occasionally under maintenance which causes a trouble to launch the tools. If you are not able to access the toolset the very next day, please do contact us.
