WALTER

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 toolset at the same time due to the waiting for other users' process to finish):

Servers might be occasionally under maintenance which will make the toolset unavailable.  In such occasion, we do recommend users to download the portable version.

TeloBase

TeloBase is a curated database containing computationally predicted and experimentally confirmed telomere sequences of species across the whole tree of life.

TeloBase is running on the servers of Core Facility Bioinformatics of CEITEC Masaryk University, Brno.
Development was supported by the Czech Science Foundation, project 20-01331X, and Ministry of Education, Youth and Sports of the Czech Republic, INTER-COST project LTC20003.
