[Treebase-devel] A columnless matrix

[Vladimir G. <vla...@du...>]

Mark's data import instructions have a fix-up step, to be run after  
the matrices upload.  As I understand it recomputes character counts  
for matrices, which are computed incorrectly during the upload.  The  
step is performed by org.cipres.treebase.util.SetMatrixNChar.

This step broke during the migration, even though it was fine on my  
testing data.   Investigating the problem suggests it may be due to a  
matrix that has no columns (= no associated records in the  
matrixcolumn table).

  matrix_id | tb_matrixid |    nexusfilename     |            
title           | study_id | taxonlabelset_id
-----------+-------------+---------------------- 
+---------------------------+----------+------------------
       3463 |             | undone-non-stepm.nex | Untitled Character  
Matrix |          |             3596

The file is "undone-non-step.nex" is not in the DB.

This matrix  comes from the pre-migration instance.

I presume it is junk that I can safely delete, which I'll do before re- 
trying SetMatrixNChar.
