+To avoid naming collisions when converting a large set of input DICOM
+files to a smaller set of MINC output files, 
+.B dcm2mnc
+automatically generates the names of output files according to various
+parameters of the DICOM file information.  The normal behavior is to
+place all of the output files in a subdirectory of the given output
+directory which has its name derived from the patient's name and the
+study date and time as follows:
+
+patientname\_yyyymmdd\_hhmmss/
+
+The individual files are named according to the patient name, study date
+and time, series identifer, and modality information as follows:
+
+patientname\_yyyymmdd\_hhmmss\_series\_scan\_modality.mnc
+
+The optional scan information includes the echo number ('e<n>'), slice
+number ('sl<n>'), time series position ('d<n>'), phase number ('p<n>'),
+or chemical shift ('cs<n>').
+
+The optional modality information consists of either the string "_pet"
+or "_mri".  No suffix is added for unrecognized modalities.
+
+The 
+.B -fname
+and 
+.B -dname
+commands allow the user to override the standard file naming behavior by
+specifying alternative output directory and file formats.  The arguments
+to these options are template strings that will be expanded to include
+information from the DICOM sequences in specified
+locations. Replacements are specified by a '%' character followed by a
+single alphabetic character, as follows:
+
+    %N - Name of patient
+    %D - Date of scan
+    %T - Time of scan
+    %S - Study ID (typically 'yyyymmdd.hhmmss')
+    %A - Acquisition or series ID
+    %s - Optional slice label
+    %e - Optional echo number
+    %t - Optional dynamic scan number
+    %p - Optional phase number
+    %c - Optional chemical shift number
+    %m - Optional modality
+
+The default file name convention is therefore given by the format
+string:
+
+%N_%D_%T_%A%s%e%t%p%c%m
+
+and the default directory name is given by the format string:
+
+%N_%D_%T
+
+If you wish to avoid creating a subdirectory, you may do so by giving a
+zero-length string as the argument to the
+.B -dname
+option:

 DICOM is a very complex format, and it is difficult to anticipate all of
 the possible combinations of fields and values that may be encountered.
