ERROR: unable to find

Dear all,
I try to use DPARSF for the first time and I get the following error message:

Citing Information:
If you think DPARSFA is useful for your work, citing it in your paper would be greatly appreciated.
Something like "... The preprocessing was carried out by using Data Processing Assistant for Resting-State fMRI (DPARSF) (Yan & Zang, 2010, http://www.restfmri.net) which is based on Statistical Parametric Mapping (SPM8) (http://www.fil.ion.ucl.ac.uk/spm) and Resting-State fMRI Data Analysis Toolkit (REST, Song et al., 2011. http://www.restfmri.net)..."

Either drag and drop or specify command line options:
dcm2nii
OPTIONS:
-a Anonymize [remove identifying information]: Y,N = Y
-b load settings from specified inifile, e.g. '-b C:\set\t1.ini'
-c Collapse input folders: Y,N = N
-d Date in filename [filename.dcm -> 20061230122032.nii]: Y,N = Y
-e events (series/acq) in filename [filename.dcm -> s002a003.nii]: Y,N = Y
-f Source filename [e.g. filename.par -> filename.nii]: Y,N = N
-g gzip output, filename.nii.gz [ignored if '-n n']: Y,N = N
-i ID in filename [filename.dcm -> johndoe.nii]: Y,N = Y
-n output .nii file [if no, create .hdr/.img pair]: Y,N = N
-o Output Directory, e.g. 'C:\TEMP' (if unspecified, source directory is used)
-p Protocol in filename [filename.dcm -> TFE_T1.nii]: Y,N = Y
-r Reorient image to nearest orthogonal: Y,N
-s SPM2/Analyze not SPM5/NIfTI [ignored if '-n y']: Y,N = N
-v Convert every image in the directory: Y,N = Y
-x Reorient and crop 3D NIfTI images: Y,N = N
You can also set defaults by editing DCM2NII.INI
EXAMPLE: dcm2nii -a y -o C:\TEMP C:\DICOM\input1.p>>

The DICOM files are in the specified directory but obviously they are not recognized. Does anyone know what might cause this problem?
Best regards
Dirk
