Hello, Thanks to data and tips provided by Patrick van der Wel, I've now (hopefully correctly) added in support for pseudo 3D data (and in theory pseudo ND data) in NMRPipe. (Such support already existed for Azara format.) It seems that NMRPipe specifies the nucleus type to be ID for these pseudo dimensions. So now the program will detect this. The Analysis program still only reads the full NMRPipe single-file format, not the multi-file format. But to get at the values automatically you need to access the multi files (since only one value, for the first plane, is stored in the single file). So when you select the single file in OpenSpectrumPopup it will bring up a dialog asking if it really is pseudo 3D (and if not it will remove the offending dimension) and what the values of the planes are. You can either type in the values by hand, in which case you don't need access to the multi files at all, or let the values be fetched from the multi files after you specify the directory and template (with the %03d) for the files. (You will see that the "template" label in that dialog is a button. If you hit that button it will let you select a file in the relevant directory. Just select any of the multi files and hit ok. Then edit the name to replace the 001, or whatever, with %03d. This could try an be a bit cleverer and do that replacement automatically but I haven't put that in yet.) I have also updated the pipe2azara script, which is capable of dealing with the multi-file format, so that it automatically determines the values if you give it the multi-file template. This script will actually block the data, so has some advantage over importing the single-file NMRPipe data into Analysis. So, first convert the data to Azara format and then import into Analysis. (Well, for smallish data files this is no great advantage.) (I also fixed an unrelated bug in pipe2azara.) At some point we ought to add in a way of specifying that the other file formats, besides Azara and NMRPipe, are pseudo ND and bring up a similar dialog, except that the values would have to be definitely entered by hand.
