RDML File Compression and File extensions The xml file containing the RDML compliant data should be stored in a file named rdml_data.xml. This file should be compressed using pkzip compatible compression into an archive. The archive can have any name, but instead of having the extension .zip it should have the extension .rdml (preferably) or .rdm. Software should be able to read compressed .rdml or .rdm files as well as uncompressed .xml files. The XML file should be encoded in UTF-8, \n should be used as newline character and a point "." as decimal separator. XML is used to be human readable. All id strings in the file should be unique short names as provided by the user. Do not use random generated strings as ids, as they should be displayed to the user for example to identify different samples. If several strings have to be combined, use a ";" semicolon as separator. This is required for example in the "excl" element in the "data" section of the "react": The different reasons for exclusion have to be separated by ";" semicolons. Do not set the value to "false" if it should be included, just do not set this element. Digital PCR measure a high number of partitions. To not overload the XML file with this data, separate table files are used that are stored in a partitions folder within the RDML zip file. The counts of the partitions must be stored in the XML file within the corresponding data elements. The table files must use tabs (\t) as column separators and dots (.) as decimal separators. A line must contain the data of one partition. For each fluorescence two columns are created. One with the endpoint fluorescence value and a second with its score. The score can be: u - undefined or not yet scored p - positive n - negative e - excluded (should be ignored) The file must have a header line with the target ids matching the fluorescence value. The first lines could look like: GAPDH\tGAPDH\tHBV\tHBV\n 3412.32\tp\t121.89\tn\n 239.23\tn\t3459.27\tp\n
