Hello!

I'm sorry if this question comes of as naive or ignorant because I'm very new to Bioinformatics. I'm trying to do an alignment with STAR and was wondering if I could access a pre-made STAR index for the mm10 genome. I was told I could do this from UCSC but have had no luck finding it there. 

So my question is, Are there pre-made STAR index files for the mm10 genome that I could download? And if so where and how? 

Thanks in advance for any help and I'm sorry to ask such a trivial question! Let me know if there's anymore detail I can give!
You can generate indexes yourself easily enough. Follow the directions here: https://www.biostars.org/p/198315/ . MM10 genome [from UCSC is here][1].

@Alex has some pre-made indexes available at [STAR Genomes site.][2] There does not appear to be a UCSC version of Mouse but there is [Gencode Mouse][3] which you can use.
