Description

Calling BIDS2Legacy using a default dataPar.json crashes.

Requirements

Calling ExploreASL('/path/dataPar.json', [0 0 0 1], 0, 0) instead of ExploreASL('/path/', [0 0 0 1], 0, 0); crashed when called for Flavor GE_PCASL_3Dspiral_Product_pharma for which a default dataPar.json is created.
This is not a huge issue as this is a discontinued option and should not be used, but we still don't want it to crash.

Release notes

We can probably add it to #588 if we manage to fix within 1.7.0
