hello all
i am new boinc user and I have problem when I want to create workunits for ModelE application(see below link https://www.youtube.com/watch?v=1qcaHVFeR_s).

./bin/create_work -appname modelE -wu_name E4M20 -wu_template templates/E4M20_wu.xml -result_template templates/test_re.xml E4M20.R

Too few var input files given; need at least 2
process_input_template(): unexpected XML tag or syntax
create_work: unexpected XML tag or syntax

E4M20_wu.xml

<!-- workunit template for the BOINC E4M20 program -->
<file_info>
<number>0</number>
</file_info>
<file_info>
<number>1</number>
</file_info>
<workunit>
<file_ref>
<file_number>0</file_number>
<open_name>boinc_app_25.0</open_name>
<copy_file>1</copy_file>
</file_ref>

</workunit>

any solution?
tnx

For starters, input (workunit) template needs to be wrapped inside <input_template> element. See Input templates.

Then you have some duplication in the middle:

        <min_quorum> 1 </min_quorum>
  <open_name>boinc_app_25.0</open_name>
                <copy_file>1</copy_file>
        </file_ref>
        <file_ref>
                <file_number>1</file_number>
                <open_name>E4M20.R</open_name>
                <copy_file>1</copy_file>
        </file_ref>

If that wasn't a copy-paste error but something you really have in the template it's something that needs to be fixed.
