Neoclxml.gz is the compressed version of neocl.xml, the XML-format for the developmental lineage classification and taxonomy of neoplasms. This version of neocl.xml supercedes prior published versions [6,7]. Because neocl.xml exceeds 9 Megabytes when uncompressed, a gzipped version of the file is provided (neoclxml.gz). After downloading from the biomedcentral site, the filename should be provided with a .gz suffix (if absent from the filename as downloaded). After decompressing the file, the file shoud be renamed "neocl.xml". The file can be viewed on current web browsers, but experience has shown that many browsers lack sufficient memory to display the entire file. Otherwise, the file can be viewed on a wordprocessor or an ascii editor.
