Dear Jesper,
Many thanks for gettting back to me.
The last line simply reads "-h, --help display help info"; please see the text I have copied, below.
I do not see any error message. I have confirmed the files are in the directory, and I have read, write permissions on them all.
I'm very grateful for your advice, and I hope I haven't made some silly mistake.
Thanks and best wishes,
Colm

topup
Usage:
topup --imain=<some 4D image> --datain=<text file> --config=<text file with parameters> --out=my_topup_results
Compulsory arguments (You MUST set one or more of):
--imain name of 4D file with images
--datain name of text file with PE directions/times
Optional arguments (You may optionally specify one or more of):
--out base-name of output files (spline coefficients (Hz) and movement parameters)
--fout name of image file with field (Hz)
--iout name of 4D image file with unwarped images
--logout Name of log-file
--warpres (approximate) resolution (in mm) of warp basis for the different sub-sampling levels, default 10
--subsamp sub-sampling scheme, default 1
--fwhm FWHM (in mm) of gaussian smoothing kernel, default 8
--config Name of config file specifying command line arguments
--miter Max # of non-linear iterations, default 5
--lambda Weight of regularisation, default depending on --ssqlambda and --regmod switches. See user documetation.
--ssqlambda If set (=1), lambda is weighted by current ssq, default 1
--regmod Model for regularisation of warp-field [membrane_energy bending_energy], default bending_energy
--estmov Estimate movements if set, default 1 (true)
--minmet Minimisation method 0=Levenberg-Marquardt, 1=Scaled Conjugate Gradient, default 0 (LM)
--splineorder Order of spline, 2->Qadratic spline, 3->Cubic spline. Default=3
--numprec Precision for representing Hessian, double or float. Default double
--interp Image interpolation model, linear or spline. Default spline
--scale If set (=1), the images are individually scaled to a common mean, default 0 (false)
--regrid If set (=1), the calculations are done in a different grid, default 1 (true)
