The obspy. The module can currently read files that are in accordance to the SEG Y rev. This functionality is not yet exposed because the developers have no files to test it with. If you have access to some files with custom headers please consider sending them to devs obspy. Nonetheless they work well enough if some potential problems are kept in mind. Most of the following also applies to SU files with some changes keep in mind that SU files have no file wide headers.
The first two methods will return a Stream object and they are identical except that the file wide SEGY headers are only accessible if method 2 is used.
These headers are stored in Stream. The obvious advantage of these methods is that the returned Stream object interfaces very well with other functionality provided by ObsPy file format conversion, filtering, Due to the fact that a single SEG Y file can contain several tens of thousands of traces and each trace will be a Trace instance which in turn will contain other objects these methods are quite slow and memory intensive.
To somewhat rectify this issue all SEG Y specific trace header attributes are only unpacked on demand by default. SEG Y files contain a large amount of additional trace header fields which are not unpacked by default. The internal reading method is much faster and less of a memory hog but does not return a Stream object.
The trace header values are stored in trace. See obspy. They will be unpacked on the fly if they are accessed as class attributes. By default trace data are read into memory, but this may be impractical for very large datasets.

If a file is too big to be read into memory in one go as all the other methods doread the file trace by trace using the obspy. Writing Stream objects is done in the usual way. It is possible to control the data encoding, the byte order and the textual header encoding of the final file either via the file wide stats object see sample code below or directly via the write method.
SEGYFile objects are written using its write method. Optional kwargs are able to enforce the data encoding and the byte order. If some or all headers are missing, obspy. It is a wise idea to manually check the headers because some other programs might use them and misinterpret the data.
Most header values will be 0 nonetheless. One possibility to get valid headers for files to be converted is to read one correct SEG Y file and use its headers. The other possibility is to autogenerate the headers with the help of ObsPy and a potential manual review of them which is demonstrated in the following script:.
