bookmark CTLPScanner A web server for detection of chromothripsis-like pattern (CTLP) in genomic array data. CTLPScanner consists of two main modules: (i) detection and visualization of chromothripsis, and annotation of the detected chromosome pulverization region and the associated genes; (ii) public array data exploration. The web interface is capable of processing input segmented genomic array data with flexible visualization options and screening parameters. Moreover, a key functionality of CTLPScanner is that besides the private data processing module, it contains more than 50 000 pre-processed public oncogenomic arrays, mainly derived from The Cancer Genome Atlas (TCGA) and NCBI Gene Expression Omnibus (GEO). The web server allows users to easily explore the chromothripsis-like genome patterns with array accession IDs and self-defined constraints. CTLPScanner provides a platform to perform large-scale genomic data analysis to unravel the molecular mechanisms underlying chromothripsis phenomenon.
