Import3D: Neurolucida v1 v3 asc parse error

[eacheon]

Hi,

It seems that Import3D has problem when dealing with v3 neurolucida file with Text labels. This is what I got.

Code: Select all

oc>
5000 lines read
parse error
itok=27774 token=string x=0 s=t35b36
line 5133: ( (Color White)

This error happens at the following:

Code: Select all

...
)  ;  End of tree

( (Color White)
  (Font "MS Sans Serif" 8)
  (   -1.65   -14.11    50.49)
  "t35b36"
)  ;  End of text

( (Color White)                       <- line 5133
  (Font "MS Sans Serif" 8)
  (  -34.79   -54.68    50.49)
  "t35b36"
)  ;  End of text
...

I am still looking into this. The "v2" asc file (according to neurolucida manual, exported from neurolucida) works ok, all the markers get ignored and warned. I guess it is kind of equivalent to the "v1" asc file dealt with by Import3D, though the header of that file says it is v3:

Code: Select all

Can some one give me a hint why the line in my v3 file is an error to Import3D? Is there a simple way to ignore them other than manually deleting them from the asc file? Thanks!

I faintly remember fixing a bug in the neurolucida version 3 reader last October that may fix your problem as well. Try installing the alpha version at
http://www.neuron.yale.edu/ftp/neuron/versions/alpha/
If that does not work, zip up the offending file and email it to me at michael.hines@yale.edu.

With respect to neurolucida file version numbers. I only know that the latest is version 3 and did not know what the earlier versions were called. According
to your comment I should change all references about "version 1" to "version 2". Although I am confused as to why the file would continue to say "version 3".
