dear Yohannes,

Yes, including the '+plot' option, e.g. `teqc +qc +plot -nav navigation_file rinex_file`,
is definitely needed given that since 13 Nov 2013 '-plot' has been the default and
'+plot' is needed to get the compact3 "plot" files:

[279] teqc +help | grep compact3
                 +plot                    write 'compact3' plot file(s)
                 -plot                    don't write any 'compact3' plot file(s) (default)

So you are saying that when you executed:

teqc +qc +plot -nav brdc0010.12n adis0010.12o

that files .m12 and .m21 were not created?  Is you data dual-frequency?
I.e. you need both pseudorange and phase data from L1 and L2 signals in order
to construct the M12 and M21 multipath combinations.

One way to quickly check: execute `teqc -O.sum . adis0010.12o`.
