TopHat question: prep_reads not found?

[liux]

I am new to tophat. so be gentle.

When I run tophat with a test yeast data set, I got an error message after "Checking reads". after 3 lines of reads info, it says:

[FONT="Courier New"]
~/$ bin/tophat '/path/to/bowtie/indexes/yeast' '/path/to/sequence/seq.fastq' 
...

	format:		 fastq
	quality scale:	 --phred33-quals
	[FAILED]
Error: prep_reads not found on this system.  Did you forget to include it in your PATH?
[/FONT]

Could someone help me to figure out what I did wrong?

Whoops, prep_reads is another program in tophat that is needed. once I add '/home/user/bin' in the PATH, it worked.
