what is the difference between "motifAnnotations" and "motifAnnotations_hgnc_v9" , and what impact will it have on the results?

[Chenchen3Chen]

I'm sorry, I'm still new to SCENIC and RStudio.

when I was running it on RStudio , it always reported following error when creating scenicOptions.

Report error:
Motif databases selected:
hg19-500bp-upstream-7species.mc9nr.feather
hg19-tss-centered-10kb-7species.mc9nr.feather
Error in eval(as.name(motifAnnotName)) :
object 'motifAnnotations_hgnc' not found;

After Report error;
NitializeScenic did create the object (object_name is "motifAnnotations") will appear in Environment of RStudio.
Then all I had to do was

           motifAnnotations_hgnc <- motifAnnotations

then run initializeScenic again. The code runs smoothly.

However, I see that others can also run it through annother line of code.

code:
data(list="motifAnnotations_hgnc_v9", package="RcisTarget")

             motifAnnotations_hgnc <- motifAnnotations_hgnc_v9

The two objects "motifAnnotations" and "motifAnnotations_hgnc_v9" are different in Environment of RStudio;

Therefore, I am very confused about the differences between these two methods, and which method is better to use.

I would really appreciate it if any one can give some suggestions.
