Transfer of Data from AC200 Spectrometer to ARX Spectrometer Computers.

I.       Log on to the ARX400 or ARX500 computers (node names - nmr400a or nmr500a).  The transfer protocol is a program called bruknet, written by Bruker.  It is neither convenient nor robust, but it can be made to work.  If you have problems with this step, try doing the transfer from the other spectrometer computer, e.g. the ARX400 rather than the ARX500 (assuming you have an account on both).  If that solves the problem, please tell the NMR staff so they can clear up the problem on the first computer.  If this does not work, please ask the NMR staff for help.

A. From a unix window (not xwinnmr)

1.   To transfer a single file with the example name of J1020F.101, type:

eget ac200 J1020F.101

You MUST! use upper case letters for the file name since all files on the AC200 computer are all upper case letters.  The first two words, i.e. eget ac200, must be lower case.

2.   To transfer several files using a wildcard designator, e.g. J1020F.*, type:

eget ac200 "J1020F.*"

You MUST! enclose the filename that contains a wildcard in quotation marks.  Bruker's wildcards on the AC200 computer are very non-standard.  The * means literally 4 characters, including spaces.  The ? means only 1 character.  For example:

*.101 would get ABC.101, ABCD.101, but not

ABCDE.101, which would require **.101 or *?.101

to get it.

ABCD?.101 would get ABCDE.101, but not

ABCDEF.101, which would require ABCD*.101

or ABCD??.101 to get it.

It is a good idea to issue the directory command at the data station using the appropriate wildcards to work this out before you start to transfer multiple files.  See the section entitled "ADDITIONAL PROCESSING INFORMATION -UTILITIES" at the end of the "Processing of Routine 1-Dimensional NMR Data -- AM & AC Spectrometers" write-up.  The directory command described there that will have the same characteristics is ADIR.

B.   The bruknet transfer may take a few minutes.  Type elog to see a log of the last several actions of bruknet.  Keep typing elog until you see that all the files you specified have been transferred.  If it seems to take a very long time, and there is a timeout message, see the NMR staff for help.  We may have to stop and re-start the bruknet process on the Silicon Graphics computer, which requires root privilege to do so.

II.      Type xwinnmr to start the NMR program.

A.  To convert these files to the xwinnmr format, type conv ac200 *.  You will have to repeat this process for every file.

B.   Once converted, the data set name is the same as the filename before the period.  The experiment number will be the extension, i.e. the numbers after the period.  The process number will always be 1.

C.  Read in the file.  For proton spectra, type proton.200.  For carbon spectra, type carbon.200.  You will not be able to do automatic referencing (i.e. sref), but otherwise process the data as usual. 

III.    The data that you transfer and convert will be located in the same data directory as the data you acquired on the spectrometer.  It will be a part of the disk usage quota for charges.  Therefore, consider archiving these data, if desired, and deleting them as soon as you no longer need them on the computer.
