I have/want Ascii data, in column/matrix format.

OpendTect supports many Ascii formats. Most loading is configurable via a generalized loading facility. Export is more limited, usually some basic options are given to export all the data into an Ascii file. For more information please take a look at the following resources:

Do you load/export directly to 'name of product'?

No, but some commercial plugins do. We do have rather tight coupling with free software like Madagascar, GMT and Google Earth/Maps. We don’t support direct access to the common commercial data management products. There are commercial plugins that do connect rather direct to those systems.

Can I load/export seismic data as Ascii (or simple binary)?

Yes. You can import/export data to/from the ‘Simple File’ format. Every trace needs to occupy one line, optionally the trace can start with a position. The input or output can be Ascii or binary. The simplest form is just a ‘matrix’ of data, with the trace sample values in the rows. For more information please take a look at the following resources:
