replace part of single string in a file

replace part of single string in a file
hi!
i have a file consisting of the following lines:
(BTW, [] = space)
.
.
.
12[]ME_T1mapping_flip30[]bshort[]f
13[]DCE_whole_brain[]bshort[]f
13[]DCE_3D[]bshort[]f
.
.
.
the list of scans starts at 1 and goes on sometimes up to 60 scans. i would like to change only the lines that contain 'whole' to this:
13[]DCE_whole_brain[]spm[]f
but the scans containing 'whole' are not always on line 13, and they do not always say DCE_whole_brain, they change. but they always include the word 'whole'.
my question is can you scan the file for lines that contain the string 'whole' and change only the 'bshort' to 'spm', while leaving the rest of the file intact?
i've used 'sed' to get up to the point shown above, but now i'm stuck on how to find only parts of a string, change them and leave the rest of the file alone.
any help would be greatly appreciated. thanks!

XmStringToXmStringTable(library call) XmStringToXmStringTable(library call) NAME
XmStringToXmStringTable -- A convenience function that converts a single compound string to a table of compound strings SYNOPSIS
#include <Xm/Xm.h> Cardinal XmStringToXmStringTable( XmString string, XmString break_component, XmStringTable *table); DESCRIPTION
XmStringToXmStringTable takes as input a single compound string and a specified string component (such as a tab) and returns a table of compound strings consisting of portions of string delimited by components matching break_component. The components marking breaks will not appear in the resulting table. string Specifies the XmString to be converted. break_component Specifies the XmStringComponent that will be used to indicate where to split string to form the individual elements of table. The most useful types will be XmSTRING_COMPONENT_SEPARATOR and XmSTRING_COMPONENT_TAB. Refer to the XmStringComponentType(3) refer- ence page for a complete list of possible component types. Note, however, that the XmSTRING_COMPONENT_UNKNOWN component is not a possible type. table Returns the equivalent XmStringTable. The function will allocate space to hold the returned XmStringTable. When the applicaiton no longer needs the returned XmStringTable, the application should call XmStringFree once for each compound string in the table, and then calling XtFree to deallocate the XmStringTable itself. RETURN
Returns the number of compound strings in table. RELATED
