that page has been unable to open

Hello, I am a student.
In lotus/statistical_analyses/cpcoa.R, there are the files design.txt, taxonomy.txt, otu_table_norm.txt, and the following three files, which I could not find:
uw_unifrac. file < - paste(results. dir, "unweighted_unifrac.txt", sep="")
w_unifrac. file < - paste(results. dir, "weighted_unifrac.txt", sep="")
bray_curtis. file < - paste(results. dir, "bray_curtis.txt", sep="")
Are they in the README. Md - # # # raw sequencing data can be downloaded here: http://www.at-sphere.com/download/lotus_raw_data.tar.gz
But now that page has been unable to open, excuse me, there are other ways to access? Thank you.
