My fast file is not found by GenomeAnalysisTK

Sir,
I was trying to run GATK but my fasta file can't be detected by the program. Though the fasta exists but it showing that the file is not exist.

My lines was:

ERROR MESSAGE: Fasta dict file /Users/ZILLURRAHMAN/Desktop/PhD/Apicomplexan/Babesia_microti/Data/Strain_Naushon/strain_naushan.dict for reference /Users/ZILLURRAHMAN/Desktop/PhD/Apicomplexan/Babesia_microti/Data/Strain_Naushon/strain_naushan.fasta does not exist. Please see http://gatkforums.broadinstitute.org/discussion/1601/how-can-i-prepare-a-fasta-file-to-use-as-reference for help creating it.
