ALMA-IMF is an Atacama Large Millimeter/submillimeter Array (ALMA) LargeProgram designed to measure the core mass function (CMF) of 15 protoclusterschosen to span their early evolutionary stages. It further aims to understandtheir kinematics, chemistry, and the impact of gas inflow, accretion, anddynamics on the CMF. We present here the first release of the ALMA-IMF linedata cubes (DR1), produced from the combination of two ALMA 12m-arrayconfigurations. The data include 12 spectral windows, with eight at 1.3mm andfour at 3mm. The broad spectral coverage of ALMA-IMF (~6.7 GHz bandwidthcoverage per field) hosts a wealth of simple atomic, molecular, ionised, andcomplex organic molecular lines. We describe the line cube calibration done byALMA and the subsequent calibration and imaging we performed. We discuss ourchoice of calibration parameters and optimisation of the cleaning parameters,and we demonstrate the utility and necessity of additional processing comparedto the ALMA archive pipeline. As a demonstration of the scientific potential ofthese data, we present a first analysis of the DCN (3-2) line. We find that DCNtraces a diversity of morphologies and complex velocity structures, which tendto be more filamentary and widespread in evolved regions and are more compactin the young and intermediate-stage protoclusters. Furthermore, we used the DCN(3-2) emission as a tracer of the gas associated with 595 continuum coresacross the 15 protoclusters, providing the first estimates of the core systemicvelocities and linewidths within the sample. We find that DCN (3-2) is detectedtowards a higher percentage of cores in evolved regions than the young andintermediate-stage protoclusters and is likely a more complete tracer of thecore population in more evolved protoclusters. The full ALMA 12m-array cubesfor the ALMA-IMF Large Program are provided with this DR1 release.
