tfconvert converts a single element, all elements in one file or
all elements of a group from one file format into an other file
format of the AstroROOT container - software system.

Input parameters:

   file:     The input filename (should have extension .fits, .root or .asro)

   name:     The element name which should be converted. All elements in the 
             input file are converted if this field is empty

   cycle:    several elements with the same name may exist in the input file.
             cycle defines the index of the converted element. The first 
             element has index 1. if cycle = 0 the first element in the file 
             will be converted

   group:    if checked all children of a group are converted. If not checked
             only the group without children is converted. The converted  
             children are placed in the file with the same filename as their  
             original elements but with the new extension.


Output parameters:

   sameDir:      the output files are placed into the same directory if this 
                 button is checked.

   outDir:       this field is enabled if the samDir - checkBox is not set.
                 This is the output directory of the first converted file.
                 If a group is converted the program created the same 
                 directory structure for the output files as the directory
                 structure of the input files.

    outFileType: This defines the file format of the output files.
    		 It can be fits, asro or root

    compLevel:   The compression level for the output files. This is not used
                 if outFileType == fits.

    logLevel:    0: no log messages
                 1: every converted group is logged
                 2: every converted element is logged
                 3: every converted group and every element is logged
                 the log message are written to standard output.

Error Messages:
  
  error during reading parameters (-3003)
        This  message  shows  that  the program cannot read its	parameter file  
        tfconvert.par.  Properly the environment variable PFILES is not set. 
        PFILES should define the path  where  this parameter file is stored. 
        During installation  of  the AstroROOT package this parameter file is 
        copied to ${ISDC_ENV}/pfiles.
        See also in the installation guide at point 3 for an example to set 
	this environment variable.
