I added a water box to the protein by sovlent-box.str.And it normal terminated and produced a CRD file without any error in output file.But the CRD file cannot display with some software such as rasmol,VMD. I really do not know what is wrong with it. The accessory here is the CRD file which is produced by the script.
There is nothing wrong with your coordinate file - it is just in the relatively new expanded format that has to be used with large systems. You have already asked about this and your questions have been answered.
