Using the AVX compilation of the latest github version (committed Aug 21 2017), and the attached alignment, run on an image of ubuntu 16.04 in a virtual box, my collaborator gets the error seen below. I'm unable to reproduce this error on the same image with the same code version - it works fine for me. Any clues as to what the issue might be?


$ raxmlHPC-AVX -m GTRCAT -p 1 --no-seq-check -s AlignedReadsInWindow_1000_to_1300.fasta -n foobar.tree; echo $?

RAxML can't, parse the alignment file as phylip file
it will now try to parse it as FASTA file

WARNING: RAxML is not checking sequences for duplicate seqs and sites with missing data!

Using BFGS method to optimize GTR rate parameters, to disable this specify "--no-bfgs"

This is RAxML version 8.2.11 released by Alexandros Stamatakis on June 2017.

Alignment has 217 distinct alignment patterns

Proportion of gaps and completely undetermined characters in this alignment: 11.10%

RAxML rapid hill-climbing mode

Using 1 distinct models/data partitions with joint branch length optimization

Executing 1 inferences on the original alignment using 1 distinct randomized MP trees

All free model parameters will be estimated by RAxML
ML estimate of 25 per site rate categories

Likelihood of final tree will be evaluated and optimized under GAMMA

GAMMA Model parameters will be estimated up to an accuracy of 0.1000000000 Log Likelihood units

Hi Chris,

could it be that the physical machine of your collaborator doesn't support AVX, whereas your machine does?

Best,
Alexey
