John,

I'm running into the same problem that you had. The NCBI Sus scrofa genome FTP site provides .asn, .fa, .gbk, .gbs, and .mfa files for each chromosome (last updated 10-12-2011).

I second the recommendation for SeqMonk. Very flexible options to analyze peak data. The author of the program posts regularly in the SeqAnswers forums and is really helpful.

Thanks very much. Your description of the "independent peaks" or peak "frequency" for MeDIP versus ChIP is exactly the type information I was interested in.

I'm using MACS for peak detection. ...
