DumbFileReader

EU-OPENSCREEN-Node extension for KNIME Workbench version 1.2.0.v202006241503 by Martin Neuenschwander

Scans a folder for files, opens a file and creates a table based on the header line, then reads in the data of all other files into this table as strings. The intended application of the node is to read in data from analytic instruments. These data files are usually presented in tabular format in text files, but may contain unexpected entries in data sets (e.g. non-numeric entries like "overflow"). This node intends to overcome this problem by first reading in all data as strings, then the data can be converted within the KNIME workflow. If errors occur (too short or to long lines), these will be noted within the data table and execution of the node will continue. 3 columns will be added to the data: DumbFileReader.filename: the filename of the analyzed file. DumbFileReader.LineNumber: the line number within the file where the data set was extracted from. DumbFileReader.Error: fine if no error occurred, or type of error detected
