Earth Science Stack Exchange is a question and answer site for those interested in the geology, meteorology, oceanography, and environmental sciences. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. SEG-D is an uncommon format. From my experience, here is how you need to approach this problem.

Close Mobile Search. IXSeg2Segy allows the user to pick first breaks manually by positioning the mouse cursor at the break point on the trace and clicking the left mouse button.
Automatic break picks can be made using four different methods. Normal Move-Out NMO curves can be superimposed on a shot to check the velocity and depth of an apparent reflector. Velocity lines can be superimposed on a shot to check the velocity and depth of an apparent refractor. Unregistered versions do not support these two features. A SEG-Y file containing multiple records can be split into single record files. Multiple files with identical length records can be combined into a single SEG-Y file with multiple records or they can be merged to create a different set of files as described below.
Keep in mind that this is a bit software that will run in both and bit windows but cannot address more than 2 Gbytes of memory or file space! A single shot with first break picks can be automatically interpreted in terms of an overburden and an underlying refractor. A straight line can be visually fit to the data to determine apparent velocity using the mouse. A single shot with a reflector highlighted and time-depth, velocity and depth shown.
The frequency spectrum can be calculated and displayed for the range of data which is shown in the graphic display. Several files can be merged: N files with M traces each are merged to M files with N traces each. For example, merging several different shot files will create several common offset gathers.
XSeg2Segy also provides for file combining.
