How to add suffix to graph write operator in SNAP GUI?

[SteffanDavies]

Hello Step Forum,

I am going to split 20 Sentinel-1 A SLC acquired on the same track during 2017. I am using the graph builder to streamline the process in batch processing. It is a simple READ -> TOPSAR SPLIT -> WRITE graph.

Is there any way in the GUI to define default output file names as for ex. [file_name]_split? So when I load 20 files in the graph, they will all be written with the _split suffix.

Thank you

You can have a look at the graph I’ shown here:

Split product bandwise into single GeoTiff files

I would like to share an example graph file which shows how to split a product into separate GeoTIFF files. Each GeoTIFF file will contain only one band. How this can be achieved is shown by the example of a Sentinel-2 product, but the approach can be adapted to other products. The example reads a Sentinel-2 L1C product, resamples it to a common resolution and then splits and writes each specified band. Only the bands B1 and B2 are considered in the graph. But it can easily be extended to the …

It is for Sentinel-2 but this is not important. I use parameterise the graph with targetbasePath and use it in the Write operator. You could do it in a similar way with the suffix.
