[EMBOSS] Segmentation fault with multiple similarity matricies in fdnadist

[Hazel Hartman Jenkins]

Hello, all,

I have a replicable segmentation fault problem.

If I run the following command;

fneighbor -datafile tinytest.dat -replicates y -outfile filefrom.fnb

using a tinytest.dat file containing;
    3
1187Aquife  0.000000  0.368385  0.404489
BB213b06    0.368385  0.000000  0.151182
BB269b06    0.404489  0.151182  0.000000

then everything works.

If, however, my tinytest.phy contains two  similarity matricies (or, for 
that matter, the one hundred bootstrap replicates written by fdnadist by 
default), like this;
    3
1187Aquife  0.000000  0.368385  0.404489
BB213b06    0.368385  0.000000  0.151182
BB269b06    0.404489  0.151182  0.000000
    3
1187Aquife  0.000000  0.368385  0.404489
BB213b06    0.368385  0.000000  0.151182
BB269b06    0.404489  0.151182  0.000000

then fdnadist returns;
<quote>
Phylogenies from distance matrix by N-J or UPGMA method
Segmentation fault
<endquote>

The fault remains regardless of the "-replicates" setting.

I am not familiar with the Emboss program; I am attempting to translate a 
Phylip algorhythm. It is possible that I am simply misusing fdnadist.

I downloaded this through the Gentoo Linux distribution, so I've 
cross-posted the query on the Gentoo forums at 
http://forums.gentoo.org/viewtopic-p-4080556.html#4080556. I'll also 
cross-post the fix.

Thank you for your time.
