filenames in PG_RESULT_XXXX folders: (with XXXX = group name)

In case of *.dat files signification of columns is explained in the first 
line of the data file.

1) pagerank_<networkname>*.dat => divers pagerank files.

networks with "_1_" represent PageRank cases and with either "_2_" or 
"_1che_" (the latter only for the small non-doubled case) represent 
CheiRank cases. The word "_double_" indicates the doubled case (for "_1_" 
and "_2_").

2) pagerank_mean_<networkname>*.dat => mean-PageRank in non-doubled space 
computed from PageRank in doubled case using:
P_mean(i)=P_up(i)+P_down(i) 
Here also "_1_" for PageRank case and "_2_" for CheiRank case.
P_mean(i) is numerically very close (but not exactly identical) to 
the PageRank/CheiRank directly computed from non-doubled case.

3) mag_<networkname>_<groupname>*.dat files => magnetization for full 
network together with K rank, K* rank, original index and names in other 
columns (of non-doubled network). 

4) maggroup_<networkname>_<groupname>* files => magnetization for 
groups together with K rank and K* rank (in reduced group space)

more precisely: 
maggroup_<networkname>_<groupname>*.dat => data file with different columns 
*.mat => some other simpler format used to create png files
*.png files with colored boxes in white back ground. Colors represent:
red=1, green=0.5, blue=0, cyan=-0.5 and yellow=-1 (or a bit lower values 
depending on max/min values of data). See also the color bar figures:
fig_bar.eps/fig_bar.pdf

For simplicity all global network files (PageRank and mag_*) are provided in 
every subfolder for each group even though they are allways identical since 
they do not depend on the group.
