Yes. Don't do it 
Write to another file, and copy the new file over the old one if you have to.

ecattominc
ecattominc(1) ecattominc(1) NAME
ecattominc - convert an ecat format file (version 6.x or 7.x) to a minc format file SYNOPSIS
ecattominc [<options>] <infile> <outfile.mnc> ecattominc [-help] DESCRIPTION
ecattominc will convert an ecat data file (version 6.x or 7.x) to a minc file format Unless the -small_header option is specified, ecattom- inc will conserve the maximum informations from the ecat header and subheader fields which will be respectively stored as attributes of the ecat-main and ecat-subhdr minc variables. By default the whole 3D or 4D volume is converted, however, ecattominc allows for the selection of slice and frame ranges to be copied. The voxel values of the generated minc file are decay corrected, unless the nodecay_correct flag is specified. Finally, blood data file can be inserted within the minc file with the -bloodfile option. OPTIONS
Note that options can be specified in abbreviated form (as long as they are unique) and can be given anywhere on the command line. General options -byte: Write out data as bytes (default). -short: Write out data as short integers. -clobber: Overwrite existing file. -noclobber: Don't overwrite existing file (default). -verbose: List files as they are converted (default) -quiet: Do not list files as they are converted. Command specific options -decay_correct: Do decay correction on images (default). -nodecay_correct: Don't do decay correction. -slices:Range of slices to copy (counting from 0). Default value: -2147483648 -2147483648 -frames: Range of frames to copy (counting from 0). Default value: -2147483648 -2147483648 -frame: Single frame to copy (counting from 0). Default value: -2147483648 -small_header: Copy only basic header information. -all_header: Copy all header information (default). -bloodfile: Insert blood data from this file.
