Here's an example of what evio2xml gives for hps_003446.evio.10, note the
57615 bank and the correct run number (0xd76).
<!-- ===================== Buffer 72 contains 217 words (868 bytes) ===================== -->
<event format="evio" count="72" content="bank" data_type="0x10" tag="1" padding="0" num="204" length="217" ndata="215">

</uint32>
And I also just now tried to just find the existence of this bank in the same EVIO file
using hps-java by modifying LCSimTestRunEventBuilder.getEventData, and
found it. Here's a code snippet:
protected EventHeader getEventData(EvioEvent evioEvent) {
int[] eventID = null;
//array of length 3: {event number, trigger code, readout status}
List<TriggerData> triggerList = getTriggerData(evioEvent);
if (evioEvent.getChildCount() > 0) {
for (BaseStructure bank : evioEvent.getChildren()) {
if (bank.getHeader().getTag() == EvioEventConstants.EVENTID_BANK_TAG) {
eventID = bank.getIntData();
}
System.out.println("-----NABO "+bank.getHeader().getTag());
if (bank.getChildren()!=null)
{
for (BaseStructure bank2 : bank.getChildren()) {
System.out.println(bank2.getHeader().getTag());
if (bank2.getHeader().getTag()==57615)
{
System.out.println("asdfjkl;asdfjkl;asdfjklasdfjkl;asdfjlk;asdflkjasdfl;kajsf");
}
And a corresponding printout snippet:
-----NABO 46
57610
57612
57615
asdfjkl;asdfjkl;asdfjklasdfjkl;asdfjlk;asdflkjasdfl;kajsf
-----NABO 37
57610
57602
So this bank definitely exists. Probably your issue is it is a nested bank.

If the job does not start with the “.evio.0” file then the user has to provide a run number via the command line or the ConditionsDriver, or the job dies. I think this is pretty clunky and prone to error (in fact it would be preferable if this is completely hidden from end users), so I would prefer if this could be done automatically on an event by event basis if necessary.
