You don't need to make a DCF file from a text file. A DCF file *is* a text file. More precisely a DCF file is just a text file where the content is organized as a collection of key/value pairs. > If > you have an example DCF file I could look at, The BSgenomeForge vignette contains the full seed file that was used to forge the BSgenome.Rnorvegicus.UCSC.rn4 package. If you need more examples of seed files, the vignette also gives you a list of more than 30 seed files that you can look at. All these seed files are text files in the DCF format, that is, the information in them is organized using the DCF syntax. > some guaranteed method > of making a seed file correctly, a video tutorial or anything that > would help, can you please send it in response. Thank you. No video tutorial sorry! The best way to make your own seed file is to pick-up one of the seed files provided in the BSgenome package itself (located in the extdata/GentlemanLab/ folder) and to modify it for your own needs. In your case, the seed file for sacCer1, sacCer2, or sacCer3 should be close enough to what you need. Finally note that the BSgenomeForge vignette in the devel version of the BSgenome package has been reorganized to reflect the fact that, starting with BioC 2.14, the BSgenome data packages don't contain masks anymore (by default). As a consequence, the vignette is simpler and probably a little bit easier to follow.

To Herve, Thank you, that helped. I tried searching in window explorer for a dcf file, but couldnt find anything i looked for the folder you mentioned and found it and i see an example now. It should be easy to modify it. thank you for the help.
