I assume that by SEGY format, you mean this one: "The SEGY data format consists of 3 parts. The first part is a 3200 byte EBCDIC card image header which contains 40 cards(i.e. 40 lines of text with 80 characters per line) worth of text data describing the tape. The second part is a 400 byte binaryheader containing information about the contents of the tape reel. The third portion of the SEG-Y format consists of the actual seismic traces. Each trace has a 240 byte trace header. The data follow, written in one of 4 possible 32 formats in IBM floating point notation as defined in IBM Form GA 22-6821. (Note, this ``IBM format'' is not the common IEEE format found on modern IBM PC's.)" I am not aware of a direct interface between ROOT and this format. However, from the description, it should be quite easy to write a few lines of code in C/C++ (via the ROOT/CINT interpreter or compiled code) to read these data sets.
