Trim a Sontek ADR adv File


Create a Sontek ADR adv (acoustic Doppler velocimeter) file by copying the header plus the first n data chunks (recognized by the three-byte sequence 0xA5, 0x11, ‘0x3c’) into a new file. This can be useful in supplying small sample files for bug reports.


advSontekAdrFileTrim(infile, n = 100, outfile, debug = getOption("oceDebug"))



name of a Sontek ADR adp file.


integer indicating the number of data chunks to keep. The default is to keep 100 chunks, a common choice for sample files.


optional name of the new Sontek ADR adp file to be created. If this is not supplied, a default is used, by adding ⁠_trimmed⁠ to the base filename, e.g. if infile is "x.adr" then outfile will be x_trimmed.adr.


an integer value indicating the level of debugging. If this is 1L, then a brief indication is given of the processing steps. If it is > 1L, then information is given about each data chunk, which can yield very extensive output.


advSontekAdrFileTrim() returns the name of the output file, outfile, as provided or constructed.
