  Hello everyone,

I am a new user of SCIRUN and I am testing the various I/O options. One that used to work a week ago (namely the .pts TextPointCloudField and the corresponding matrix) does not anyomore, and I cannot figure out why! What I am doing now is a very simple, small and dummy example like this:

1/ I have a file named "test.pts" for the TextPointCloudField (7 lines) and I use a "FieldReader" module to read it:

cat test.pts

6
0.0 0.0 0.0
1.0 0.0 0.0
0.0 1.0 0.0
1.0 1.0 0.0
2.0 1.0 0.0
2.0 0.0 0.0

2/ i have a file named "test.dat" for the TextColumnMatrix (7 lines) and I am using a "MatrixReader" module to read it:

cat test.dat

6
1.1
1.2
1.3
1.5
1.6
1.7

3/ I am trying to view it by

- importing the .pts file through a FieldReader as a TextPointCloudField
- importing the .dat file through a MatrixReader as a TextColumnMatrix
- merge them using the ManageFieldData module

4/ I am getting an "exception" in the ManageFieldData module reding the following:

===============================================================
REMARK: Input field contains no data, no output matrix created.
ERROR: Module crashed with the following exception:
ERROR: c(value=1) == 0(value=0) (file: ../src/Core/Datatypes/ColumnMatrix.cc, line: 225)

5/ Can you please let me know what I am doing that is wrong? I had tested a similar case last week and it worked...

  Thanks a lot,
  Vasileios.

PS: I have both an RPM installation and a "from source" installation and both give me the same problem.
