Hi, dear members. I faced a problem when I used R package TIGRE. Because the Rdata stored in the package is about Drosophila. I really want to have a look about its data structure; in this way, I can figure out how to form my annotation or other necessary data types, and input my microarray data, which is about a plant pathogen, Gibberella zeae, different from the insect Drosophila. As the I don't manually annotated the genome of our fungus, so I want to input my annotation file into R and combine this file with my microarray file, then I can carry out transcription factor target identifications. Would do you please give me some suggestions? Thanks

The following is the results of R, and I really want to know the structure of the data `drosophila_gpsim_fragment`.

Have you tried the `str()` command?  It will let you examine the structure of an object.
