Dear Zhang,
Depending on your problem, these parts of the code do not require any modification for field data application. A successful FWI depends more on the estimation of an accurate initial model and reasonable data preprocessing. I produced an extensive tutorial video series on the application of FWI to a near-surface field dataset: NGP Course “Seismic Full Waveform Inversion” - with the caveat that the tutorials are currently only available in german. Perhaps they are still useful ...
Best regards,

Dear Daniel,
Thank you for your quick and informative response to my question. I spent most of today watching your NGP Course "Seismic Full Waveform Inversion" tutorials (especially tutorials 8-13), and l found them to be incredibly helpful and inspiring.
Now that I have obtained the initial velocity model for field data, I am planning to use a code similar to raw_data_sort.m
(if possible, and if not, a similar code) to segment and preprocess my segy data and obtain the corresponding observation system. I then plan to process the segmented data(.su) and acquisition system with the DENISE Black Edition for FWI and RTM.
Do you think this plan is reasonable? Could you please give me your advice on the next steps?
Thank you again for your guidance and expertise.
Best regards,
Zhang
