test fails after new install

[mathog]

Greetings. On CentOS (64 bit), installed in /usr/local automake 1.15 autoconf to 2.65 then, successfully
installed redundans (according to the log file), but the test failed. Suggestions? The devtoolset-4 is needed for a compiler which is recent enough to understand all the g++ command line switches. Typically programs produced this way need no special treatment when they are run.

cd ~/src
scl enable devtoolset-4 'source <(curl -Ls http://bit.ly/redundans_installer)' 2>&1 | tee redundans_installer.log
#worked!  Says to test it like so:
cd redundans
./redundans.py -v -i test/*.fq.gz -f test/contigs.fa -o test/run1

Suggestions?

Thanks.

[mathog]

Hmm, the numbers in the run above do not match those in README.md. Significant or just the documentation being slightly out of sync with the software?

[mathog]

Inserted this before the original line 136 in fasta2homozygous.py

print "DEBUG 136 identities", identities, " sizes ", sizes, " i ", i #DEBUG

and reran the test. The log file now has:

In other words, "hits" in fasta2skip the 2nd time it is called is empty. The first time it was called there were some of these. Is no "hits" the 2nd time a reasonable result for this version of the code? Even if that is not itself a problem, the code should handle that state, which it does not. So that much is certainly a bug.

Other than these debug related changes the output is the same.

Did a clean install on a CentOS 7.4 system. Compared to previous system:

Python 2.7 in /usr/bin only (previous had it in /usr/local/bin, with 2.6 in /usr/bin)
lastal not in path (previous had a version of lastal in the path)
bwa not in path (previous had a version of bwa in the path)
parallel not in path (previous had a version of parallel in the path)
perl 5.16 in /bin/perl (previous had 5.20 in /home/mathog/perl5/perlbrew/perls/perl-5.20.0t/bin/perl)

That looks like it might be correct. It diverges from the Centos 6.9 run at iteration 1.2 in scaffolding. Tried to make the 6.8 environment more like that on Centos 7.4 with:

cd ~/src/redundans
export PATH=.:/bin:/usr/bin:/usr/sbin:/sbin
ln -s /usr/local/bin/python2.7 python
# lastal, bwa, parallel no longer in path, python 2.7 is, perl 5.10 is
rm -rf test/run1
./redundans.py -v -i test/*.fq.gz -f test/contigs.fa -o test/run1

Same results on this system as before.

Examined the contents of ~/src/redundans/test/run1 and found that the directory structure was different. On both there are directories named "_sspace.1.1" but the contents were not the same. The one which worked had:

There are also many more _sspace.1.1* in the run1 directory on the one that failed than there are on the one which completed. Bizarre.

The 7.4 system has bash 4.2.46 and the 6.9 system has bash 4.1.2. Hard to believe that matters.

I don't see any error messages in the log files in run1.

Suggestions???

Thanks.

On a second Centos 6.9 system, which mounts my ~/src from the first 6.9 machine, and has pretty much identical software, the test was run again. This uses the exact same redundans install that was unable to complete the test on the first machine. On this machine it completed, but the results differ from the Centos 7.4 machine! Here is this 3rd set of "test" results:

Comparing the two Centos 6.9 machines...

PATH: identical
alias: identical
bash: same version 4.1.2
python --version: 2.7 (failed) 2.7.14(passed) [Centos 7.4, python 2.7.5]
site-packges: probably differences
perl: same version (same binary)

The directory structure in test/run1 when it ran well on the second Centos 6.9 machine matched the
Centos 7.4 machine, not the first Centos 6.9 machine (where the test failed).

[mathog]

Figured it out! Version numbers on failing machine were NumPy(1.9.2) and matplotlib(1.5.0). The similar 6.9 machine which worked had 1.13.3 and 2.1.0. So upgraded to NumPy(1.14.0) and matplotlib(2.1.1) on the problem machine and afterwards the redundans test would run to completion.

The test results are not stable from run to run though, ie:

rm -rf test/run1
./redundans.py -v -i test/*.fq.gz -f test/contigs.fa -o test/run1 >/tmp/run1A 2>&1
rm -rf test/run1
./redundans.py -v -i test/*.fq.gz -f test/contigs.fa -o test/run1 >/tmp/run1B 2>&1
diff /tmp/run1A /tmp/run1B

and they differ in many lines.

Hi, Thanks a lot for solving that!
Yes, I've noticed that individual runs may produce slightly different results - this is due to snap-aligner. It's super fast, it runs in multiple threads and I guess the differences comes from the fact that snap-aligner outputs reads in ambigous order (depending which thread finishes first), while redundans process only certain number of reads to speeds the things up, so some reads may be included and some not in individual runs. Using BWA MEM was giving stable results, yet it's much slower, especially for larger genomes.
