Anoop, if you search the list archives at https://www.jiscmail.ac.uk/cgi-bin/webadmin?S1=spm for the error message you encounter, there are 27 hits. Most suggest you make sure to remove all traces of possible older analyses that might confuse spm, make sure that all data is available for all subjects, check the mask image in order to make sure there is enough overlap between subjects, look into defaults.fMRI.stats.ufp, etc. To paraphrase myself, "in a way, this error tells you something is wrong with the dataset", so checking data and data quality should be the first thing you may want to look into.
