matrix factorization toolkit not writing out output files

[premgopalan]

hi,

I tried nmf and pmf as shown in the blog post below, and no output files are being written out. It appears to train and converge OK, but the U and V files are missing. http://bickson.blogspot.com/2012/12/collaborative-filtering-with-graphchi.html

./toolkits/collaborative_filtering/pmf --training=x_mm --minval=1 --maxval=500 --max_iter=10 --pmf_burn_in=5 --allow_zeros=1 --R_output_format

./toolkits/collaborative_filtering/nmf --training=x_mm --minval=1 --maxval=500 --max_iter=100 --quiet=1

I am having the same problem with pmf.
