Data acquired on instruments in CIF is archived in several ways, depending upon the instrument. Much of the archived data makes it's way into the CIF Research Data Cloud. This is space managed and maintained by ISU Information Technology Services; we pay a small monthly rental fee. Within the cloud you will find directories for each Major Professor... leading to directories for each researcher in the group... leading to directories for each instrument... leading to actual data files.
You cannot write to data files while they are in the cloud; reprocessing data will require you to copy the files to your local computer. Attach the CIF Research Data Cloud as a network drive (typically it will show up as the Z: drive on your computer) and then simply drag and drop the files to your local PC or Mac. (MNova softare does not require write access to process data, so you will be able to process data without copying it to your computer.) The procedures for accessing the CIF Research Data Cloud are discussed in this PDF. If you have recently started at Iowa State or joined a new research group, you may not be authorized to access the CIF Research Data cloud, and you will need contact Sarah to gain authorization.
Procedures for reprocessing previously acquired data will vary from instrument to instrument. Please speak with the appropriate CIF staff person to discuss your personal needs for data archival, retrieval, and reprocessing.
X-ray Single Crystal Structure Determination
All single-crystal x-ray diffraction final results are available in the CIF Research cloud. The full framesets are typically very large files and they are archived on DVD's. If you would like to have a copy of framesets, please send a request to email@example.com.
X-ray Rowder Diffraction
Data acquired on the Scintag powder diffractometer is available in the CIF Research cloud. Copies of files are also kept locally on the Scintag operation PC. You may also want to copy your data to your flash USB drive in ASCII (text) format as the size of all resulting files is very small.
Once NMR data has been acquired, we encourage users to process their data using MNova, Topspin or VNMRJ on one of the four processing stations in Hach Hall or two processing stations in Gilman Hall. This reduces wait time for other users when instrumentation is busy. Your data will be instantly available at the processing station once you save it on the spectrometer computer. All data acquired on the NMRs is kept locally for at least a year. Your files are also moved to the CIF Research Data cloud as soon as you log out of the NMR. This allows you to immediately access data from your office, lab or home computer. In order to process your data, you will need to install MNova and obtain a copy of our site license or install another suitable NMR processing software on your computer.
Mass Spec Data
Data acquired on the mass spectrometers is kept locally for at least a year to allow for reprocessing in the lab at the instrument computer or the associated data processing station. Most of the data is then archived in some form (CD, DVD, et cetera) depending upon the instrument. At the moment, data is not archived in the CIF Research Data cloud. The LC/MS data is archieved using an external hard drive. At the present time we intend to use external hard drives for data storage. Eventually we will add the ISU Cloud storage capability.
Data from the various spectrophotometers (IR, UV-Vis, CD) is kept locally until the file system either fills or fails. The data is not archived in the cloud.
Elemental Analysis data (CHN/S Analyzer) is kept in hardcopy form, filed by date. The raw data can be typed into Excel for reprocessing if necessary.
