Dear Conn expert,

in preprocessing part of our data analysis i have these error. 

ERROR DESCRIPTION:

Error using read_hdr (line 32)
Error reading header file

i found older forum thread https://www.nitrc.org/forum/forum.php?th... but the solution not work. I try to change conn version from 17f to 18b, and the error is still the same. The main part of all these problem is in the data file path. Conn add "c" prefix to the name of folder not to the file. 

conn try to found file in these path with non existe folder with "c" prefix (red c in path):
"/hydradb/hydra_io/vypocty/ADAMEK/ART_DMN_conn/Source/cARTDM_C01490_20171002_1541_1/
0019_t1_sag_mpr_3D_CONNECTOM/20171002_154109t1sagmpr3DCONNECTOMs019a1001.nii".

but the right path for these file is:
"/hydradb/hydra_io/vypocty/ADAMEK/ART_DMN_conn/Source/ARTDM_C01490_20171002_1541_1/
0019_t1_sag_mpr_3D_CONNECTOM/20171002_154109t1sagmpr3DCONNECTOMs019a1001.nii".

without c prefix. 

im not able to found right solution. 

Thank you Petr
