it seems that dcm2niix might be trimming ProtocolName in the .json file

```  
"ProtocolName": "func_run-05_task-passivelistening_acq-4",
```
which later is complemented by dcmstack with 
```
"ProtocolName": "func_run-05_task-passivelistening_acq-404tr",
```
under global:const section  .... we need to check with dcm2niix
