#4 “Running the multi-zone nucleosynthesis code” failed.

[Anonymous]

Hi! Prof. Meyer,
When I adopt the project you provided (https://bitbucket.org/mbradle/simple_sn2/src/master/README.md), I successfully complete the "Compile the codes by typing" (./project_make) and "Run the explosion code" (./simple_sn2 --libnucnet_xml work/example_data/s25_pre.xml --output_xml expl.xml 1.2e51), but I get the error when I run the "nucleosynthesis on the output of the explosion code:"(./multi_zone_network --libnucnet_xml expl.xml --output_xml out.xml "[@label1 < 200]" ""). The error is as follows:

"Running the multi-zone nucleosynthesis code." failed.The error is as follows：
./multi_zone_network --libnucnet_xml expl.xml --output_xml ou
t.xml "[@label1 < 200]" ""
neutrino_e is not a valid neutrino.

How should I solve this problem！

Eager for your answer！
Best wishes!
