Default Email Address for emaildata and vnmremail

The macro commands emaildata and vnmremail have been modified to use a default email address defined by a VnmrJ parameter email. If you have an indiana.edu email account and prefer to email files to there, you don’t need to change … Continue reading

Open FIDs Without Autoprocessing

By default, VnmrJ is set to automatically process NMR data when a FID file is opened. If you prefer to process your data using the parameters that were stored in your FID file, you can do so. All you need to do is to … Continue reading

Setting Temperature vs Actual Temperature

Actual sample temperature could be different from displayed temperature (or setting temperature if the temperature has been regulated), especially at very high or very low temperature. We recently re-calibrated the sample temperature for all spectrometers, and wrote a macro command … Continue reading

Using 3mm NMR tube

If you have a limited amount of sample, you can use 3mm NMR tubes to reduce solvent volume therefore to increase sample concentration (by a factor of 3). You can get 3mm NMR tubes from the Chemistry Storeroom. To use … Continue reading

Email NMR data

You can email .fid data files from spectrometers or workstations within VnmrJ using the command “vnmremail(‘filename’,’email address’)”. For example “vnmremail(‘/home/doebrown/test.fid’,’doebrown@indiana.edu’). The files are compressed and archived into .tgz format (tar + gzip) so you’ll need an archiving utility program on … Continue reading

Using array to acquire a series of 2D NMR

As we know, array in VnmrJ can be used to optimize parameters for data collection and to acquire a series of dataset, which are not limited to 1D only. For example, for backbone dynamics measurement, 15N R1, R2, heteronuclear NOE, … Continue reading
