Error using gunzip>gunzipwrite Coregistration


I'm running into issues during the coregistration step. 
I get the following error: 

Error using gunzip>gunzipwrite (line 234)
Unexpected end of input stream when attempting to GUNZIP the file
Error in gunzip>gunzipEntries (line 154)
    names{k} = gunzipwrite(entries(k).file, outputDir, baseName,
Error in gunzip (line 90)
   names = gunzipEntries(entries, outputDir);
Error in DPARSFA_run (line 1601)

Error in gui_mainfcn (line 95)
Error in DPARSFA (line 30)
    gui_mainfcn(gui_State, varargin{:});
Error while evaluating UIControl Callback.



Any suggestions what is going wrong?
