Re: [Gdcm-hackers] CStore problem while try to save the same file second time with few changes

[Mathieu M. <mat...@gm...>]

Petchirajan,

  I found the issue in the DataSet. Look at the following tag:
0018,6011 in your dataset:

(0018,5027) UN 30\2e\35\39\30\30\38\33\32\34            #  10, 1
SoftTissueThermalIndex
(0018,6011) UN fe\ff                                    #   2, 1
SequenceOfUltrasoundRegions
(0019,0000) UN ba\01                                    #   2, 1
PrivateGroupLength


  Could you tell us how you use the GDCM API to generate that ?

Thank you very much !
