In IVE 3 and IVE 3.3 prior to June 1999, image data written by IVE on a VAX system was automatically detected and converted without user intervention. From June 1999 on, IVE 3.3 no longer has this capability and when VAX data is read the floating-point values in the header, extended header, and data will be garbled. The command-line utility vaxmrc2mrc can be used to convert the data file to a form compatible with IVE 3.3. vaxmrc2mrc takes two arguments. The first is the name of the input file, and the second is the name of the output file. The conversion is not done in place and the input file name and output file name should not reference the same file. As an example,
vaxmrc2mrc oldvaximage.dat image.dat
reads the file oldvaximage.dat from the current directory and writes out the converted result in image.dat in the current directory.
